My Mystic Color Classic is up for sale on eBay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=51046&item=5114016307&rd=1&ssPageName=WDVW
It has the 575 board, 640x480 mod, 68MB RAM/2GB HD, etc.
I've read the CC forums on here for a while, but never got around to posting. Hopefully someone from here can enjoy my Mystic.
