I just saw this on eBay... Someone is selling a lot entitled COMMODORE 128 COMPUTER AND MANY EXTRAS (http://cgi.ebay.com/COMMODORE-128-COMPUTER-AND-MANY-EXTRAS_W0QQitemZ110105027952QQcategoryZ74945QQrdZ1QQcmdZViewItem), and hidden amongst these "many extras" is a Promenade C1 EPROM burner. The last few Promenade C1's I've seen sell on eBay have sold for around $300, so this is a chance for someone to get one for much cheaper, plus get a lot of other hardware along with it. :)

Wow. I hope I remember to check this in a few days and see what it's up to.
I have a PC-based burner already..... I guess Im not *that* much of a collector :)
