I'm using the RSP1a, and I have two of them to cover more of the FM band. It's been fine for FM and 90% fine for MW/LW. RSP2 doesn't offer the width I need for FM. Elad or Perseus are out of the question cost-wise. I can only use MW/LW at our annual DXpedition due to proximity to strong locals, high noise level and terrible tree placement, so my primary use is FM.
