Check with D-lite here in the forums. This is his site, http://multimods.com/ I have recently been doing business with him, and he is a pretty cool guy. Drop him an email from his site, and he will get back to ya. Price is reasonable as well. His site has not been updated in a few, but he is still there working on modding/refurbishing systems. Just bought a modded Duo-R, with RCA jacks and LEDs. I was pleased with the price. Look into it.
I had a good experience dealing with RedGhost as well for the same mods recently. Here is his website.
