What are you used too? Different styles seem to suit different people.
I can't get to grips with a dynaking angled head style but Luurve the Renzetti vices. I currently tie on an Abel vice which i got for the hook range.
Don't think they make them any more, But i used to use a Renzetti presentation 3000 and it was fantastic for trout flies, i changed it Because i needed a bigger range.
Now i'm home i would happily swap the Abel for another Renzetti 3000.
The renzetti traveller vices are brilliant and good value and i think if i had £250 to spend i'd get one of these , the range is less specific than the 3000 ands it covers loads of sizes.

If you like pivot head vices The DYna Kings are mostly in Budget and they are Built to last and awesome quality.
Lots out there and you will likely get different ideas from different people, try to figure out where you sit your hands when you tie and that should suggest what will be comfortable
