I need a no contract phone for 6 months - WP8?

I lost my freakin' phone. Dammit. I had the Nexus 4, no contract with T-Mobile (in US). $60/mo, 4GB 4G, unlimited everything else. Great deal. (And no fees or taxes! $60/mo for reals, and no data limit, only throttled after 4GB)

Perhaps while I wait for the new phone crop to come in, I can try out a cheap Windows Phone. Any ideas?
