ushopwireless.com seems to have the best deal right now - it's free after rebates, but their reputation seems a bit shady. Any advice?

Thanks!

Also keep in mind that coverage is much more important than cost, so if you are planning to switch from Verizon to T-Mo, you really need to look at which carrier provides you the best coverage where you will use the device - where you live, work, travel and play. T-Mo's coverage is much less than Verizon and ATT, hence the cheaper prices as they try to gain market share. You may find out that Verizon might be your best bet.
