In 2011, I bought (2) DMX dongle in 2 different coops [ one was pcb and the other was case ] plus had to order parts from mouser for them ... my total cost was around $75 per dmx dongle ... which makes the etherdongle seem like a steal. Probably if I hit the right coop for the entire dongle, could have saved maybe $10 each. As it is, I didn't even max out the capability of a single pixelnet flashed DMX dongle this year, which gave me 4096 pixelnet channels.
