Where can I find a cheap CD printer?

I definitely would not recommend either of these products. They both only print black and the second one only operates on batteries or optional AC adapter, so you have added expense there. I would recommend a Epson R280 (I do not know where you live, but in the US they retail for $99.99). It is a 6 ink printer that allows you design and print (in color) onto printable CD/DVD's. Excellent quality photo printer as well.
