Finally bit the bullet after wanting one of these for quite some time (but laughing at $299 price tag well before they came out finally) and placed an order for it on Newegg.
$159.99, no tax and free shipping, and getting $15 back with an Amex deal... if you have sync, #AmexNewegg on twitter and good to go for purchases over $150.
Essentially $145 from a no hassle return policy reputable place, and new. Worth the $20 over what I would have paid with that eBay link and tax.
Hope it works perfect with my mini display to DVI monitor, if so I'll be very pleased! This, my two USB 3.0 externals, and using third usb to my usb 2 monitor hub (which at this point will be only keyboard since I'll plug ethernet in too and set my moonrise USB ethernet stick aside), and access other USB 2.0 ports if need be.
Thrilled to tidy up my desk and make tethering and untethering (No, not jailbreak

) to my desk a quicker process than plugging up both USBs, mini display, and power!
Going to get one of these as well:
