Ebay seller, adrenaline_cycle, has two RC30 items up for sale. How about a vintage tool kit in an old-school fabric wrap: $1000 or offer plus $20 shipping. They also have a set of used mirrors, stated to be "factory OEM" though they're in black and the mounting doesn't look right, at least for the 1990 US model: $600 or offer plus $15 shipping.
For a potentially better deal on the above tool bag, here's a set up for auction, opening bid at $499.
From France we have a used 8-spoke rear wheel for a cool $862 plus $145 shipping to the US (current exchange rate).
Having recently completed the paintwork on Project 41, I can verify that the cost of paint and labor has also transported those costs into a new realm. It's all relative, of course, and we play with old motorbikes for nobler reasons, right?
