Default [Q] Changing from AT&T to Sprint, need advice

Greetings all.

Not 100% sure if this is the right area but I have to start somewhere.

Currently with AT&T and have been for many years. I am now settling down in one area and AT&T sucks in the area. Sprint is the logical choice since blanket coverage and others are happy with Sprint..

Going the the new Sprint $60 all you can eat plan.

My main requirement will be tethering since my only option for internet is very slow DSL.

If you were in my shoes, which android phone would you choose from the Sprint 24 month contract line up? Like a good solid phone that is easy to root and load with custom ROM.

Also what custom ROM would you run?

Many thanks for the input and I value it more than you know.
