I've owned a number of vises over the two decades I've been tying and sold only one in disgust (a Danvise, whose jaws were just not strong enough for tying big flies that required the pressure needed to spin deer hair). That said, I still have my first vise, a Renzetti Traveler, to which I've added various components and which still accompanies me when I...wait for it...travel! I've added a couple more higher end Renzettis (bought used or on special) and they get used as well. The other brand I have consistently found nearly flawless is Dyna-King. I use the Dyna-King Ultimate Indexer at home and just purchased a Dyna-King Professional as a backup. Follow RexW's advice (always a good idea, I have found), but realize that if you stick with tying, the first thing you will upgrade is your vise. It's the key to good tying.

Still liking the Peak Tying Vise... added another pattern to the playlist - Quick Tie - Simple Midge.
