I've just come across a guy on eBay selling a couple of these units and some other bits, prewired/upgraded, thought it may be of interest to anyone looking or about to buy one of these machines:

The wiring can be one of the "let downs" on these types of machines, the price seems pretty good and even better is that the machines are in the UK, so no getting stung on import?...
