HackRF comes to mind. You can occasionally find good deals on Ettus gear on eBay/forums/etc.

  HackRF is only half-duplex, and the turnaround time isn't fast enough to fake it. You'd need two.

    It's going to be cheaper and easier to just buy a radio that can do full duplex -- the LimeSDR costs about the same as a HackRF, and is nominally supported by OpenAirInterface.

      HackRF clones cost much less, and there is no LimedSDR clones AFAIK.
