Exactly what I was thinking.

I've been using a Darex V290 (V390) that I picked up at a yard sale for 50 bucks a few years ago. If you trace back the lineage of all these one-and-done fixture grinders you'll probably stumble on Darex, for one. I'm a semi-decent sharpen by eye -kind of guy, but for small drills, the V290 is very handy, and for all sizes, it does a great job with its standard grit CBN wheel.
I have two complaints with the Darex unit:
a) it is awfully slow. Maximum removal is a few thou off the cutting face for each setting, and
b) the finger-type collet holder used by Darex is way too fussy to set up and prone to sticking with grinding dust.
My compromise to deal with a) is to hand sharpen (say, in the event of a corner chip) and then fine tune with the Darex. For touch ups, it works great as designed. For b) the collet system that these Asian copies are built around seems like a genuine +1 to the original design. For now, I'm stuck with the finger style.
Having a second wheel as backup in case of an oopsie is probably a good idea. Replacing the Darex CBN wheel on a 30+ year old machine is not economical since they keep changing the wheel dimensions and angles. Consequently, they are proprietary and expensive. That may or may not be the case with the offshore units in 10 years, but I'd like the insurance if I was going to spring the cash for one.

I've spent a few years chasing after decent darex grinders at auction, with nothing to show for it.
For all my brother's manta of "I sharpened bits by hand when I was working as a machinist" he hasn't done squat to my stash of excellent bits that just need sharpening. Lacking that skill myself, a sub $400 brand new easy peasy bit sharpener is a no brainer.
Why wait for a miracle find
I have a
Me too. Just can't seem to get it right. I bought a Drill Doctor 750X. Seems to do an OK job but I just don't trust those length setting fingers......
If I didn't have the 750, I'd cough up for the Vevor too. Given time and maybe a few 750 failed uses, I may sell the 750 cheap and buy the Vevor.
I've resigned myself to never sharpening endmills. For the years I have left it's cheaper and faster to convert dull/broken endmills into pins and buy new ones.

I've never broken an end mill... I've worn one out sure... but I've broken way too many drill bits that could have been resharpened so I think this is going to be my best purchase of 2024.
Here is a special video for you and @DavidR8
sell your DDs while they still have some value
Ooops wrong video.
This is the one

Buy him some really good pot and set him in front of a grinder with a bucket of bits. Put on some good 'ol banger 'tunes and come back in a couple hours. Job done!
I quite enjoy sharpening bits if I'm in the mood for it, but for some reason it's one of those things I have to make time for. Which never happens. Usually, it is when I actually need one to do a job, and then it adds 10 minutes to the job!

Nah neither of us smoke...
I have the vevor now, and I can sit in my basement with all the old bits and just grind thru the task with minimal effort with the right set up. This is why I'm making a sit/stand work bench, so I can adjust the height, the arm supports and such so that I dont have to bend my spine or other joints for long periods of time.

I picked up the MR-13b model a few months a go but really wanted the expensive VEVOR MR-20G
I had a good look at it and figured its an identical machine function wise and was only missing another collet holder and a few oversize er 20 and 25 collets ( along with spaces in the front to store them) ..... so I found them and ordered them.
er25 collet chuck oversize er20 and er25 collets
The only other thing I could think of adding was the holder from the MR-13a which allows a different point to be ground in, as per Mr Pete's videos on the matter.
oh and while you are at it get some collet holders to print

The Drill Doctor got its following not from the cheesy new version that he shows in the video but from this older version that they produced for many years. A great little machine, now I have never sharpened a 135* drill on it so I can't speak to that.
The older version was made out of that thick Makita type plastic that not even Makita uses anymore.
I p/u mine new on ebay for $40 usd about 8 yrs ago.
I'm sure the Vevor unit is superior in every way and I'm tempted get one myself before the price goes up.
But if the Vevor is out of your price range older versions of the DD are still available.
