I own a variety of vises, but currently tie on the Renzetti Traveler. I also favor the Anvil Apex. Both are solid vises and within your price range.
I just did a tying demo at a local fly shop and was chided for not using the rotary feature on my Renzetti, but I just don't feel like it saves any time or effort in my tying and I do tie a lot.
P.S.: There are worse "vices
" than tying flies...
(I just couldn't resist, sorry
