I've only used 3 "kits" and they were from my LHBS... now I just make up my own. Once you get the hang of it... it's easy and fun. So check with your Local Home Brew Supply store.
There a re lots of vendors here with lots of kits. I'm sure you really can't go wrong with any of them. Northern Brewer, Williams Brewing, etc...
Welcome aboard and happy brewing!
