I had to pick one up for myself, if I had more free cash I would have picked up extras.

If you aren't familiar with the HummerDTV at Radio shack, it is based on the C64DTV rev2, but has user port lines and apparently no joystick lines. It overall appears more advanced and hackable than the DTV rev1(original US version). On the downside it has the same color issues as the Pal DTV, but can be corrected.
Some hacking upcomming! If there is any interest I will take pics of my project as it progresses.
