Dev 1 set/ plans/ pre-paid?

Hello!

I have combed the forums trying to piece together the info I am seeking, and now thought I would try just asking in one place.

I have a Dev Phone 1 handset from Google, which was gifted to me and came with a limited-time T-mobile sim card with data/cell plan. It has now expired.

I want to get a new plan, and would like recommendations on the best carrier to go with-- I am guessing Verizon in light of their fairly recent partnership with Google. But perhaps there are other considerations to take into account? Can I insert any carrier's sim card into the Dev 1 handset?

Most important, I would like to find a pre-paid plan that includes data...anyone know of such a plan offer from any carrier that would work with Android?

Thank you Droid Phans and Experts! I appreciate your input!
