Thanks everyone for the replies ^_^
Yeah, it's bizarre (to say the least) that anyone would AV mod a Jag, considering it already outputs RGB signal natively (which I guess is worlds better than AV).
I'm very afraid to buy this particular console only to find out the RGB signal has been killed by the mod...?
The reason I'm willing to take the risk is because this is particularly a "cheap" Jag, as far as prices go here in Brazil (consider the 2.2k price tag is in Brazilian currency - much weaker than USD).
An un-modded console here is north of 2.5k, which I guess I'll take a look at.
Ebay should be an option too, but most US and European sellers won't send it overseas, so maybe I'm stuck with local sellers afterall...
