We got into TechStars in Boulder in 08, but before that we were couped up in the upper west side trying to make it happen. Had there been a TechStars in NYC, we probably never would have relocated to Boulder. There's something to be said for the fact that the NYC community isn't as swamped with startups yet. That's not to say you'd be completely lost in the SF noise, though, because YC definitely helps with that.
