Hey I actually have a Duo R in the box. It has s-video, new laser on it, and a region mod. Bought it with the intention of RGB purposes but it wasn't working out, though every other aspect works wonderfully.
Only catch is, I won't be near it until May 6, so about 2 weeks. (I'm away at school and will be moving back home soon). If you're interested and can't find one in the meantime, maybe we can work something out!
