Picking internships is difficult

I realize there is only so much complaining I can do about having to pick the best of a number of good options, but it is still hard. Here's whats been served up to me so far:

- Internship offer at Endeca Technologies in Cambridge, MA. Sounds like a great opportunity, they work in high-powered search technologies, and Boston is a great city.

- Fog Creek wants to fly me down to New York for an in-person interview. Honestly they would be my #1 choice, but the Endeca deadline is in a week, and only about 1/3 of candidates they fly down actually get hired.

- Rockwell Collins has an interesting project (some kind of in-cockpit LCD touch display) that I got a callback for, but I think I'm ready to move out of aerospace after 3 summers doing that.

I'm going to sign the acceptance letter for Endeca tomorrow, but I'm disappointed that I have to turn down Fog Creek. But in the end I think I would be taking too big a gamble to turn down a confirmed, good-sounding internship for only a chance at a great one. Mostly I'm disappointed that I don't get a free weekend trip to New York City, especially since they are one of the only places that will actually pamper interns while recruiting them.
