Well if you want the best, get an older Wilton. I have 3 that I lucked into. The biggest one retails for about $1300-1600.

I did
NOT pay that for them. I feel a quality vise is
THE FOUNDATION of your shop. It is the one thing you need even before something like a drill press. I have grown sort of a weird affection for them, and have decided that I cannot have too many

You'll be able to see this is in upcoming work in progress I'll be doing with a collector. I guess I have a vice for vises.

BTW- Thanks for using the right spelling!!!
This is the new version of my big, fancy Wilton. It's the Mercedes/Tank of the vise world.

Deker is spot on... mass in a vise goes toward rigidity, which is what you want. My big Wilton weighs about 185 pounds (note that's about 30 pounds heavier than the new version). And I have a HUGE Rigid brand 8" that weighs about 220 pounds!!!
HOWEVER!
I have an el cheap-O, Harbor Freight swiveling head vise (regular 5" bench jaws on one side, pipe jaws on the other) that I honestly could not do without. I have been using it for 14 years and love it.
I paid $35 for it. I think you can find them now for about $50 but the ones I've seen aren't nearly as solid as my older one. This is mine, on my old bench. I just painted it to match my blue Wiltons
Whoa! I just found the vise I'm talking about... price went up! And it looks (just by the photo) like it's a lighter duty (less stout) version compared to the one I have.

I would definitely use Craigslist for a vise search as well! :thumbup:
