If you're just getting into SDR, I would just get a $20 RTL-SDR, and then move on to something like the HackRF or BladeRF later.
The Red Pitaya is a particularly compelling alternative from a hardware hacker's perspective, because it does double duty as an extremely versatile measurement and data acquisition device.
been lusting after one of the little guys for some time now.
I'm also kind of salty that they dropped the MicroUSB variant of the full-size model. The Mini makes sense to have it a "stick" format, the full one does not. The full one having an A connector on it has been nonsense from day one.
I still will probably end up buying one because they're still the best bang for the buck.
