I just mentioned a CIS at the make do thread, lol. I have seen some good deals over at Amazon. I am probably going to build mine though since I already have the inks.
I remember when I used to post at the digital crafting forums the girls used to have good resources for CIS systems. I bet one of the Digital Scrapbooking forums might have a listing. That was a long time ago when the 12x12 printers were around $500.
