You are right; for the purpose of dvd recovery, if it works on all 360, that will be a good reusable chip. Still I think most glitch chips will be going into slims as a permanent install.

Found a new glitch chip at http://x360glitch.com/, seems to come in 3 version, slim one cheapest at only $9.81.
Still uses a xilinx but board layout looks different. Has anyone tested it yet?
