Newbie, I think that the article on vises was online @ www.flyfisherman.com.
If I remember correctly the Dan vise was best under $100 & I can't remember any other price ranges.
IMHO, the difference between a pedestal & C-clamp vise in use is flexibility. With a pedestal you don't worry about scratching up the edge of the table you are tying on and can have the vise in from the edge. It also allows you to stop tying 1/2 way through a fly and just move the vise to the side or put it up high out of the kids reach.
