Nope, never thought of PC engine, I'll see what I can whip up, and am also open to any other ideas, so long as the graphic is fairly simple.
Most sign shops that do edge lit would charge $70 to $100 or so for something like this, but they'd be nailing you mostly for the designing charges, which as I said, are not a factor here for something this simple, and something which I may sell a few of. They also do a pretty drastic markup on materials, and charge a set rate for machine time, usually on the order of $75-$100 an hour. At prices like that, nice as they may be, I don't think many would want them.
I'm cutting another one as we speak, with the curved radius corners, I'll post a pic when able ,,, This one should be a production model, with clean edges.
1/4 plexi has its uses, its cheaper, readily available and probably easier to make a custom stand for. The etch looks just as good, but the design appears to "float" more in the 1/2, due to its thickness ... And also yeah, when the thin stuff is shipped it needs to be boxed, else it will easily fracture. The 1/2 is very solid, you couldn't crack it without making quite an effort to do so. It is basically like bullet proof glass, so if you should happen to drop it, it would not crack ,,, Though they are obviously very prone to scratching and collecting finger prints.
I should have a sale/trade thread up within a couple of days, I genuinely appreciate the compliments coming from fellow turbo heads.
