I use a Tipton Best vise. It is decent. However, I have yet to fund anything that looks more solidly built that would take its place. It works well but the flexing of the plastic when clamping the stock does concern me about its longevity.
What I use the most is the basic entry level Tipton. Mine is 20+ years old and is actually grey and blue and marked Midway. These work much better than the so-called "Ultra." The "MSRP" is $65.00 but you can find them pretty much anywhere for less than forty.
