Like SI74 said mate, just keep an eye on ebay and the classifieds. The price you'll pay for reps you'll be able to get a decent set of genuine 2nd hand ones. I was looking for RC's for a while but I've changed my mind and want something different now but there were plenty of sets about at the time. I just never had the cash for them.
When searching eBay search for bbs rc and bbs anniversary, the latter being the best one. However sometimes people do list them as bbs rc too.
