We've very heavy voice users, so needed lots of minutes/month. We've had great luck with Boost Mobile... I particularly like their retention policy which is NOT to lock you up on a 2 yr contract, but rather, to reduce your bill after N months of on-time payments. (Started at 60/mo, and after about a year we're paying 45/mo for unlimited voice+data+text.) On the other hand their customer support sucks if you need any help beyond the self-help on their website. AFAIK they do NOT have any live support.
