Problem for me has been the price for light strings plus controller plus software coming out for over $200. Much better than before, when we only had iColorFlex and other high end pixel strings for $500 a string and thousands for the controllers and software. But still a bit beyond my reach right now. (Hoping I can manage to scrape it up in the next month or so. Best bet is D-Light Firefly with LOR demo, if possible).
