Mute,
I'm not nearly as experienced at tying as most of the guys here, but I have also been bitten by that bug (pun intended). However, i would like to give the following advice. Also, I don't know how experienced you are at tying, so don't take this advice as in insult. It is just general advice for anyone who wants to try it.
In my opinion, the tying kits are not the way to go.
First of all, you end up paying for a lot of stuff you will never use.
Secondly, I feel that the materials and tools that you get with kits are typically low quality or might not be what you end up liking.
I bought a lower price kit. It did get me started, but if I had it to do all over again, I wouldn't have bought the kit. I still have some materials that came it, and probably will never use them, and I have replaced every tool that cam with it.
Here is what i would do if i were starting out all over again in this order.
1. Buy a tying book.
2. Buy a decent vice. You don't have to go crazy and spend big bucks. A good one can probably be had for under 50 bucks. Mine cost me about 20 from Cabela's but it was quite a few years ago. Nothing fancy, and doesn't rotate, but has two different size heads.
2b. Also purchase a few tools, like a couple bobbins (and get ones with ceramic insert), and a whip finisher, hackle pliers. These are just suggestions. Some people recommend learning the whip finish by hand first, but I can't say it made it any easier.
3. Then i would pick out a few simple flies from that book that i want to try first. For example... Wooly Buggers, pheasant tail or hairs ear, and adams. Then I would buy only what I need for just those few patterns. And don't forget the head cement. And by the way, Sally Hanson's Hard as Nails nail pollish works fine and cost less.
4. Find a friend who already ties and have him help you out a little bit. In fact, you might want to look at this as the first step. That friend more than likely will be glad to provide what you need and help you tie a few to see if you will enjoy it. I know i would. That is what a friend did for me. You will also get an idea of what tools you need and maybe what tools you like or dislike. Then go buy the stuff. Once you learn just a couple basics, you will be bit.
Once you get good at it, go ahead and buy a fancy vice. The less expensive one will make a nice backup.
