Since the HackRF is open source, there's a group that makes a lower-cost clone called the HackRF Blue: http://shop.hackrfblue.com/ http://shop.hackrfblue.com/. Their model is $215, and they have some units that have some minor issues (can transmit jut fine) for $150. I haven't used the HackRF Blue, so I can't compare it to the HackRF One. There are a few comparisons floating around the internet.
