What you've been told so far is all good advise. I can only speak from my experience, and I've only tied on 2 vises. That said, I can also say that I've seen a lot of different vises, my job has me traveling and I stop at all the outdoor stores I can. I'll keep it as short as I can. The good vises start at about $100 and go up. These will be at your desk for many years. The cheaper and knockoff vises show their weaknesses when side by side with good vises. A rotary isn't absolutely necessary but it's a very good thing to have and makes tying a lot easier. Anvil Apex and Atlas are both good machines under $150, as is the peak and some of the Renzetti's which I use. I can drop names for a long time, but the one thing I can tell you is to handle several before you buy, and be PATIENT. This is like choosing a woman, you want to get it right. You won't regret the time spent, and the one for you will stick in your mind as you look at the others. Good luck in your search.....Skeet.
