At the time I thought you were nuts to pay that much for a vise, how times have changed.
About a year and a half ago I was in a position to buy a decent vise and the Glacern was on the list but by the time I paid exchange and shipping I could buy a Kurt (4") locally for about $100 more. I bought the Kurt and have absolutely no regrets.
Being able to clamp a 6" wide part in a 4" vise without rearranging the jaws,,,,,,, priceless. lol

If it's something you're going to use seldom then an inexpensive tool is probably the way to go. If it's something that will be used often the it's worth buying a decent tool that works well.
But, it comes down to buying what you can afford and be comfortable with.
