Sanyo SCP-7200 / RL-2000
Best Buy availability
I know for a fact that this phone is in Radio Shack. I saw it in the store myself. I have seen it in the Richmond, VA Radio Shack stores. I'm not sure where you are located. Maybe it's just available at certain Radio Shacks in large metropolitan areas. There's about 20 or so Radio Shacks here in the Richmond area.
I also know that it is listed on eBay for $150.
This phone is very much like the Nextel i530 or i230. I forgot the series number.
I'm a GSM customer, but if I wasn't I'd buy one of those. I'm somewhat of a techie, so I read a lot of the magazines and reviews on these phones, etc. Sprint has great phones, but there service is not that great from the experience that I had with them several years ago.
