William,
I have one or more of each one mentioned. Plus some others. Don't let an absolute $100 price point be a road-block. Do you need 6 meter reception? If so, go SDRPlay RSP1A. If not, consider the AirSpy also. The latter has a hole there:
HF coverage between 0.5 kHz .. 31 MHz
VHF coverage between 60 .. 260 MHz
I have 3 SDRPlay models and 2 AirSpys. Each has their strengths. If you're new to SDR receivers, go with the RSP1a.
