I bought a discounted Bebop 1 (well below $200) about the time it was replaced with the Bebop 2. It's got GPS (albeit not an especially good one) and RTH. My reason for buying (apart from the discount) was that it's immensely hackable. Although, to hack it you need to practically deactivate the built-in control software. That's not as bad as it sounds, as there is working open source control software available, which you can use as a starting point for your own experiments. So, if you should stumble over some shop that is still trying to rid themselves of their old Bebop 1s, you might want to take it into consideration.
