I can't afford one but thought I would pass along the kewords for fidning them on eBay. Search using:
iRex Iliad document ereader UNUSED + 1 gig SD card
They have I think 3-listings. I have no idea what gen they are or anything. But since they seem to be kinda scarce I would pass info along...well, that and since I can't afford it right now I can share with the class....
BTW, I have zero clue about the seller as I never have bought from them so cannot vouch for anything on that side of the deal.
Anyway, if it is a deal I hope ya enjoy them...maybe this fall for me...
