That's the nature of the RF business. Most folks are interested in one (<= HF), or the other (> HF), or have money for equipment that handles both. Building good equipment that handles the full spectrum is challenging.
You'll also note the prices, and that those are receive-only devices. Some of the reason the price is so high is that we did all the RF design in-house, designing to our specs. A lot of the cheaper boards out there have less amplification, no (or too little) filtering, and use an integrated LO/mixer/digitizer/baseband chip, which limits them to the specs that chip can handle.
