I thing the Easylase is the cheapest professional Solution this Time.

But also there something new is in the Pipeline:

"EasyNET ", an Ethernet USB Controller with DMX, 5 Colorchannels, Ethernet Connection and much more Processorpower like the Easylase. I think it is finished in 6-8 Weeks. This Time there is no Software which can Controll this Card but I try to integrate it in LDS .

Sure its no Hobby-Solution . It will be about 2 Easylases . . .
