People seem to have very good luck with the kits from Austin Homebrew Supply, morebeer.com and Northern Brewer. The advantage of kits from a high-volume retailer like that is that you know the ingredients are super-fresh. LME in a can particularly seems to start tasting like the can (and darkening) after a relatively short amount of storage time.
The kits don't come with yeast--since you apparently have a LHBS, you could even purchase your yeast locally if you want.
