I'm selling them assembled, mostly due to the tiny SMD components. It's also a real pain to get the polarity correct on all the LED's.. I'd say I had a 30% success rate in the 10 boards I assembled. Luckily I have a hot air rework station, so flipping them around after getting them wrong isn't too big of a deal for me. I had the boards produced by iTead, they were pretty quick, and put up with me not having a clue how to make proper gerber files, as well as selecting the wrong size board.
