Seriously, my favorite shop right now are the Gore tuners. Incredibly convenient. I haven't handed them a core shot yet, but, for simple stuff, I have been very happy, and, the price is right. I had two pair done a few weeks ago, and it was about 50 bucks. But, more important, I did it while I was skiing. (of course, this won't work if you only have one pair) They work fast, too. They promised the second tune, which I dropped off around 1pm, in 20 minutes. I said, hey, no whoop, taking like three runs anyway.
Also, they tune for the obvious conditions right outside their door, instead of some mythical conditions some dude in Westchester might imagine are existent up north.
Tip them well. They deserve it. Cheerful service, too.
