I have a new (almost never used) 1400cs/166 with no cracks at all both, small floppy drive and cd drive, plastic cover and all power cord, boots perfectly, want to sell it for a reasonable price to someone who loves this piece of history.
Suggest to try Ebay which will also give an approx idea on how much you should be asking. Or when you have the required number of posts or days of membership you can post on this forum's 'MarketPlace' where it may sell.
