What's wrong with Airspy.us ?
My Experience With RTL SDR V3

Thank you! I had no idea that there was a North American supplier. All of the auction listing are from the U.K.
Many thanks! I've heard the most positive feedback about Airspy products so I'm going to invest in one this weekend
Unfortenetly most iof the SDR's ( not only the rtl-sdr-v3) suffer from very low immunity to strong signals
as sonn as you connect them to outside antenna they receive all the spectrum with a lot of intermodulation
of course uou can download the RF gain but then you will get poor sensitivity so be happy that it is not only the RTL-SDR that behave like that but akso more expensive radios the air spy os not much better although it have 12 bit ADC the big advantage i see on it is the wide span

With "the air spy" you probably mean the Airspy R2 with a max. bandwidth of 9 MHz.
The Airspy HF+ Discovery mentioned in this thread has a max. bandwidth of about 0.9 MHz.
Both have quite good RF filtering, so they overall do much better than cheaper RTL-SDR sticks.

The Airspy HF+ Discovery is a strong performer at frequencies below 35 MHZ, but if you are interested in frequencies above 80MHZ the SDRplay RSPA1 is more sensitive has a larger bandwidth and covers more frequencies and is less expensive.
Airspy HF+ vs. SDRplay RSPduo at MURS Frequencies.
