Hard to find imperial size
Some people like to have an over/under set so presumably could handle situations like a light press fit or a light running fit. Personally I feel its a way to burn through a lot of money without a specific purpose in mind. There are so many classes of fit, types of shafts, IMP vs Metric. I would pick a brand you like & buy them as you need them. Places like KBC sell some good USA names & also euro (house brand) both are good. Its similar to taps, don't buy junk grade or you will regret it.
In small size metric I have been experimenting with AliExpress & so far been quite impressed.

Looks what i would like...I got some hand reamers from these guys that didn't break the bank...
Asia & Europe are predominantly metric, so you are kind of stuck with N-Am suppliers if that's what you are after.
But again depends on what you are doing. If you have a 0.250 ground shaft & want 0.0005" diametric clearance, you need a 0.2505" reamer. So it's Imperial-ish, I guess you could say decimal Imperial. But many folks think they need a 0.2500" reamer because its 1/4". My question is for what purpose? Ground pins & drill rod have +/- tolerances so it may not be good for intended purpose. Hopefully this makes sense. Trying to save you money LOL

Look at PROCUT for the less expensive stuff.
Compare prices, you might find KTS is expensive. (just a spot check, I didn't look in detail)

For example my next project will be to make a lathe bed stop and i want i want to have an indicator in it.
Do i need a reamer or only a drill bit will make the job?
Hmm, I could go either way on that. Holes are kind of considered roughing operations so surface may not be perfect for indicator stem. OTOH if its a cheapo $20 indicator and ideally clamp style retention, maybe drill is OK. Number/letter drills are pretty fine increments (and also mic your stem beforehand). You could test drill on scrap & evaluate for yourself.
This is a good way to hold indicator stems

Is the M2 version really worth the extra $200 over the regular HSS version? I guess it depends on what you're reaming.
I was thinking I needed reamers a few months back and after diving deep into clearances, over/under, metric v imperial, I ended up at the same place as PeterT
I figure it's better to wait until I really really need them and buy exactly what I need. Having said that, I was trolling ebay round xmas time and found a semi used 7pc 1/8 - 1/2 by 1/16ths set for $20 so I snapped that up. Still haven't actually used any of them yet though, so... kinda reinforces PeterT's point...
