Not mine, and from the pics there's no way to tell if they're the EX, SX, or BX model
(the EX has the most hardware features while the BX has the fewest
), but at less than 25 USD including shipping these might be worth a look:

The Nova 5000 is a pretty nice device as far as CE 5 devices go, and if it's the EX like most of the models showing up on eBay have been, it's a real bargain. It should be pretty easy to find a universal power adapter that will work with this device
(it's 12 volts, with one of the standard tips
).
