Apex models can order what you need generally. I have not had any problems with parts so far!
SO, i would say EBAY is not the be all and end all for SC stuff. people should stop relying on a rip off auction site( iuse it and its great but damn expensive to sell on) and look to local model shops for spares and help......
I love the hong nor, and would only replace it if schumacher did a SC..............
