When the Pluto came out, I had to have one. Playing with it kind of left me saying "meh" because it didn't seem to have much RX gain. I needed a beam to focus on the transmitter.
I then tried the LimeSDR-Mini but that thing only lasted about a year and then failed. Expensive junk. Comparably, the Pluto is much more hobby oriented with the ability to run Linux. Still running after several years. It's not cheap at $250 USD, but think of it as a Pi combined with a radio.
