100 bucks per pop bumper?
I realize the parts cost on these is relatively high + that harness you've come up with, and I've tried to do this mod myself, so I know how fragile these things can be and getting the plasma separated from the little control box they come mounted to is very difficult without destroying the wires that go into the glass. Pretty sure your "collar" is totally necessary to give clearance for the glass nipple on the back..good idea putting some lighting in/on it.
But man, we're talking about nearly the same price as an LED Color DMD...or a sheet of invisiglass.....I just....oof. I'd love to have these in my Voltron project(All the lightning crackling around when they join up..) because the pops area is SO SO crappy on WPT and it would fit my retheme, but I'm going to have to think about whether or not I want to sink that much money into what's just a cosmetic thing. It's hard to say the price isn't justified because of my own failure to do this mod myself twice, it's just a bit hard to swallow. At least one of us figured out how to get the bloody things apart successfully.
