2 problems with the ones on eBay (or just about anything you're getting on eBay).

1. How do you know they're the real deal, and not fake? By the time they get to your house, they may look like DC5 ITR Wheels, but they're way too heavy...
2. $250 S&H. Ouch!

*Edit*
The DC5 ITR Wheels on eBay right now are offered by: dc2_88
Now, while his % is good, look at the bad comments left by buyers:
not authentic as described, but a decent delivery.
Disppointed in quality - not ethentic as described
the top is a fake it is a rip off dont buy of this seller
buyer beware Watch didn't work promised replacement never came an excuse will
