$55 no contract, with everything I need...
I've had Virgin Mobile here for quite a while. Sprint coverage is more than adequate. $55 gets me unlimited talk, text and data. The data is apparently throttled at some point but I have yet to pass 1GB in monthly usage anyways and have never been throttled.
I use a lot of voice (over 1500-2000 minutes most months), else I would go for a cheaper plan.
I have *never* regretted dropping my contract plan.
