I love my Danvise. I picked up a generic pedistal base for it a year or so ago at Cabela's and will never use a clamp again!
As far as materials, I try to buy some stuff from my local shops, but also buy from Feather Craft, J. Stockard, and Crazy Angler Tackle. Crazy is a jig tying site for the most part, but I love their chenilles! All three I have listed above have A+ customer service!

If you're looking for patterns to tie, check out the archive here, Fly Fish Ohio, Charlie's Flybox, and Ward Bean's Warmwater Fly Tyer sites.
