I've been doing some mild research (for when I have to migrate my RP/Ting account) on pre-paid phones and services and I came across what looks like a good deal on mySIMPLEphones.com (It's affiliated with Simple Mobile.) The specs look good for the price. You can buy the phone alone or with simple mobile plans (there are some current promotions on plans on their site.)
I'm not sure when this deal will expire.

There is no model number listed but a google search shows it's probably the TG-L800S and it's listed at $229 on Ebay and Walmart and a ridiculous $348.99 on Amazon.
(More specs on other websites: Qualcomm Snapdragon 801 MSM8974AC, 2900 mAh Built In battery).
Hope someone finds this useful. Seems like a good deal.
