It's great to read the comments here about my experience. (Fyi, there's no official agency that bestows the title "power-user," so power-users are indeed self described.) THE POINT of this isn't just "if it's too good to be true" (which it's not), but that when buying anything-anywhere-anytime, it's incumbent on the buyer to (a.) verify that what you got is what was represented, and (b.) buy from places (virtual and bricks-and-mortar) that offer real guarantees, and (c.) understand that on eBay, the customer can almost always win a dispute. The comment by Joel was 100% accurate - I've bought a lot of stuff on eBay, and filed a fair number of disputes. I've won every dispute without any problems.

NOW... a geeky answer about the "if it's too good to be true" comments: In Android, one can root the device and then reallocate more ram using the device's internal storage (flash) memory. While this will probably slow down your device, it can also provide you with the ability to run some memory-hogging apps. This was particularly good for devices that had only 1gb of ram (and yes, I've done this, but unless you're ok with the possibility of bricking your device, this stuff isn't for the casual user).

So, in reality, with flash memory being so incredibly cheap, these tablets were a good price, but definitely not too good to be true. When I started searching, I was expecting to pay about $15 more - around $80.
