The blades are already around 3.3 I think (from SSB if you buy 9) and USB miners are now around 0.12 from couple of resellers here. So given that and some delay with Canary's new GB, I think we'll see closer to 0.1 for the USB miners and 3.2-3.4 for the blades.

Under .1, is a great buy for something in-hand in couple of days. Even if it has a negative ROI, it is still better than the "promises" of the other pre-order miners. Plus for $10 or so this is a great xmas tree ornament! (if you decide to quit mining)...or a stocking stuffer, heck... use it for Halloween instead of candy!
