So your 3 incredibly short posts since joining here are: I want an RC300, I want an RC300 and I want an RC300. Why not try joining in the community, entering into conversation with people, build this site up a bit and then maybe people may keep an eye out for one for you - it's a give and take thing here, not just gimme, gimme.
Why not tell us why you want one, what bought you here, what bikes you've owned in the past, maybe even put a post in the introduction thread on the forum so we know a bit more about you other than the fact that you want a RC300
