Hi, i have done a search on here just to see past threads and hope this isn't a very repetative theme

I have been tying fairly regularly for a few years now and feel like i am fairly proficent?
In my mind a vices main job is to simply secure the hook and not to much else? (please enlighten me if you view otherwise?, don't want to sound ignorant).
I currently use a basic lever vice, i was looking to up grade to something fully rotatable recommendations please?
Also clamp or pedestal? what are the main advantages/advantages of either?
Budget is a consideration and some of the considered are
Snowbee - flymate
Regent - traditional (clamp or pedestal)
Veniard Deluxe - no 1
I have also seen one on ebay looking very similar to the snowbee but including a bobbin craddle for half the price?
Thanks in advance jon
