For Sale is one 6GB microdrive, which fits in a Compact Flash Type II slot. This drive is a pull from an iPod Mini, is in good working order, and comes with a compact USB adapter which allows you to plug it into any USB port and use it almost like a flash drive (which makes transferring between camera/external device and your computer fast and easy). I tested this device in the middle of typing this, and it works.
$45 shipped (to the US/Mex/Can - perhaps slightly more overseas), or I will (would prefer to, actually) trade for a working Linksys NSLU2. They key word here is "working" - coming without original box/documentation, with slight cosmetic damage, or with Unslung already installed is acceptable, as long as the device reliably works.
I'd also consider trading for a new or remanufactured toner cartridge for a Brother HL-2140. This, however, would have to be in its packaging.
