If it matters to anyone, PFRAN is a longtime MUD vendor with vendor star. He was one of the first to start selling these kits for the 100 series. I had a 48 panel LED burn out and when I tried to order another one, he wouldn't accept payment and sent me 2 panels for free.
Get Outside's contact might be great too and all the kits are basically the same. It's a cheap upgrade for sure.
