The best thing to do is buy the best vice you can afford and avoid the ones that sell for less than $80.00. You don't need a rotary, just get a good, well-made, stationary vise, and as a bonus, they are quite a bit less pricewise than good rotary vises. Cheap vises are false economy because they don't hold hooks nearly as well as well-made, slightly more expensive ones and they don't hold up. The best lower cost vise I'm aware of is the Griffin 2A, or its slightly bigger brother the 3A. Both are less the $100.00 new.
You can also look around for a quality used vise. Vises like the Thompson Model A, which was used by a huge number of commercial/professional tyers before vises like the Renzetties and Dyna Kings came on the market. They can be found for around $40.00 or less.
If you are convinced you need a rotary, there are several very good ones for between $125.00 and $150.00.
