I checked out the listing. He seems to know his products, as far as paper and ink. When going through his feedback, he recently bought a heat press. No way to know if it is the one he's selling unless he says it's new.
BUT he also just recently bought a C120. Look at the price he paid, wow, I didn't realize the newer model could be had so cheap on Ebay.
EPSON C120 COLOR INKJET PRINTER NEW! - eBay (item 140237987051 end time Jun-08-08 14:14:07 PDT)
(I just checked and the c120's are on there cheap, some cheaper than this.)
Whatever he is doing, he is up to something, not necessarily bad either. He may be just buying supplies cheaply, and bundling them as a package for profit sake. On the other hand, he may be rebuying stuff to replace his faulty stuff, and selling his used off in a auction. Toss a coin.
If he doesn't say the stuff is brand new, then he must be keeping the brand new stuff, and selling something he already had there. Look in his feedback and you'll see what he purchased along with more info on a press he recently purchased. Like I said, can't tell if it's what he has listed in the auction, but it could be. The description is rather vague in the listing he bought it in.
