I have no EBay clones (thats somethign different in my opinion). I just use a PICO 328 and a Seeeduino Mega.
Why?
The PICO was one of it's kind back then (Small form factor 328, way before an official one that way) and i just like the seeeduinos more due to their breadboard and prototype board compatibility, mini usb and auto-reset features.
