Skip the kit.
Buy some quality, but low cost, tools.
Then, buy the materials you need for the flies you know you want to start with, the stuff you're gonna use constantly. Start there.
As you feel creative, add more stuff.
Ergo, you need a vise, a bobbin (go ceramic), scissors, head cement, bodkin, and probably a whip finisher (materelli style is generally easier for most).
Look at the flies you lose the most, I'll bet its simple nymphs (hare's ear and pheasant tails), buggers, and some sort of dry fly.
Skip the dry out of the gate, you'll make him as an advanced lesson. Start with the former. Buy the stuff you need. Some lead, some beads, wire the feathers and the hooks for the sizes you need. A colour or two of usable thread.
Go crazy, gives you an excuse to do bi-weekly runs to the tying shop, buying the things you need for the next pattern.
-or-
Buy a kit, use half of the stuff, replace a quarter of the stuff in the first six months, and never use the final quarter. However, you'll have a raft of things to try and use and thus won't be limited. I did this method despite everyone telling me to do it the other way, I wish I'd have listened, but it turned out just fine.
For the former, try a smaller shop that won't try to jam $100 vises and $20-per Wasatch tools down your throat, for the kit, either works, I started with a $80ish Cabela's kit, I think.
