Sanyo SCP-5400 / RL-2500

Does anyone know if this phone or the RL2000/SCP-7200 phone will be sold at Best Buy? Someone wrote that the RL2000 is available at Radio Shack and its listed on their website, but I can't find a store location that has it to even get a look at it. Also, sprint's site says these phones are only available through Sprint stores?? I have an older version of the RL2000 (the Sanyo 4900) which I bought at Best Buy and I want to upgrade with either the RL2000 or RL2500 but must do it through a BB store. Any help would be great.
