Which SDRs would you recommend at the $100, $300, $600, and $1200+ price points?

I’m not an expert but I know of a few. Are you looking at recieve only, or transmit/ recieve? What frequency ranges?

Off the top of my head

HackRF one- relatively cheap, pretty good transceiver, lots of crappy clones

USRP B205mini, expensive, fast, closer to pro equipment

		I like my HackRFOne, but be aware it's half-duplex, so it can transmit as well as receive - but can only do one of them at a time. For a little more money you can get full duplex SDRs, which opens up a bunch of extra interesting sttuff you can do.
