I wil argue one other thing that Jack said. Don't get a cheap bobbin (depending on what he meant by cheap). the one that came with my kit was junk, and would cut the thread. Get a decent one preferably with a ceramic insert. They still are fairly "cheap."
As far as my earlyier message. i was talking about kits with materials when i said don't buy a kit. As JeffK pointed out, noting more frustrating than trying to tie flies with poor quality materials, plus when you figure out what you will actually use, you aren't saving anything. However, i wouldn't buy a "tool kit" either. I haven't seen one that has all the tools that i like, and most contain tools that I don't like.
If you go to a fly shop, they have lots of tools, and usually they have somebody who can show you how to use them. Take whip finishers. There are many differint types. Some i like, some I don't. You can pick out the one you like ater they show you how to use them.
My vise is a Cabela's Master Vise. I think it came with three different heads. It works fine for about 30 bucks. Nothing fancy, but it holds the hook. They have feedback at Cabela's web site. Some feedback was poor, some good, some average. All I can say is it works fine for the money. However, I would say the really cheap ones are a waste of time and money. There are certainly much better vises than the one I have, and someday i will upgrade, but for a beginner and for the simpler flies that I tie, the Cabela's works fine.
Definitely get good scissors, and you can't have too many different ones IMHO.
Also Mute, you asked what materials should you buy. It depends on what you want to tie first. Jack gave good advice IMO.
If you are going to buy just one neck (because they are so expensive) I'd get grizzly because it looks the buggiest (to me). You can ften substitute it for others in a pinch. Trout can't read recipes. You can even tie Adams without the brown and they look fine. I haven't been sued by a trout yet for leaving out the brown. Here is another idea. sometimes you can buy two halfs in two different colors for aout the same price. Or, you can go halves with someone else, and buy two and split them down the middle.
For larger dries (size 14 and larger), the Saddle works fine IMHO, and is easy to work with. They are softer, but work for me. Saves some money.
Gotta go.
Great discussion.
