Get the Curt Scott book to start (go to the Cobra Country Web Site). Get the latest edition (its been rewritten a few times) to get some idea who's making the kits now (and construction styles). 2 biggest factors are money, and goals (what you want the car for - racing/cruising/show). Prices range from $25k to $100k. Do not overlook resale value (check the prices for used Cobras on this web site for examples). Another good source for info is the "forum" for each manufacturer you're considering (look at the problems/solutions those kit owners encountered).

And, finally, no matter how good you think you have figured your budget, add 20%.

Almost forgot, the waiting list can be a factor too, some manufacturers can provide the kits right away; some you have to wait for (supply & demand).
