What Fatman said is spot on. I have had my hands on several and there are several good ones, but there's also many that look good til you start moving or adjusting or putting pressure on them. Peak, Renzetti, Apex, griffin, all make good vises. Plan on a hundred as a starting point, but don't buy because of the price. You're going to spend lots of time with this, make it time with a smile. A few extra bucks opens a few more doors.
