I guess that to folks who've recently got hold of a machine (especially looking the direction of the prices), 5-6 working Memotech MTXs sounds fantastical! Of course, not all were bought recently or on ebay, so I understand the amount spent wasn't extreme... but if you're new around here and just paid 200-300 GBP, for example, for your machine, I could imagine jaws hitting the floor!
