Anyone know a reputable place to buy these?
In the US there seems to be a number of Ebay listings for Z11 preorders, though you're going to pay a pretty steep premium through those sellers as they jack up their prices due to import fees and PP/Ebay fees.

You could also make a WTB post for a Z11 in the Computer Hardware section (

it is best if you live in the united states to establish a gray import through canada. it will be so much cheaper than buying it in ebay. in addition, defective shipments are often sold in ebay.
