I recently got a Mini S12 on a lightning deal. $240 with a $40 coupon and a $47.80 lightning deal so $152.20 in the cart. The WiFi doesn't work for me, but I'm otherwise very happy with it. I use it as a headless server so I can't comment on it as a desktop. If the fan in it breaks I may be SOL for support, however. It is nearly silent which is great. Check out its price history.

I also have an older MeLE PCG02 and its WiFi doesn't work either so I think it is a common driver issue with some of these machines. I haven't looked too hard into that as I just plug them into my network switch. You'll see they also have a $30 coupon. I'm not sure why these brands like to use coupons so much. Check out its history.

There appears to be plenty of healthy competition in this market so you can probably snag a good deal if you keep an eye out.
