I've got a SLC3100 and a SLC3200 for sale. Both are in really good condition. The 3200 has a minor crack on one corner. Both have minor wear on the plastics from rubbing in a case. I just flashed the tri-soft images on them so they are pretty much stock now. I just don't use them enough any more.
The 3100 comes with a ambicom wifi cf card that I modified to use an external antenna. I used this zaurus to track down rogue access points in my previous job. Somehow in my move I lost the original power adapter for it, so I'm replacing it with an iPaq power brick. They're identical voltage, I've used it for a couple years at work to charge my Z. Still has the original box and manuals. It's also has a screen protector on it's whole life.
The 3200 comes with a planex cf wifi card, no modifications to this one. Also has an extra unopened battery. This guy has a minor crack on the corner, but it doesn't affect the use. There isn't a screen protector on, so there's some minor swirls from cleaning, so minor I can't get a picture of it. Still have the original box, manuals for this guy as well.
$300 for each, or $500 for both, plus whatever it will cost to ship them.
