Hey there, I should be picking up your kit from the CNC either today or tomorrow, and then the slot cutting & packing will take place over the weekend. It will ship Tuesday, you'll get an email from FedEx with the tracking number.
I can send you some templates to make some art up. I like to get my art printed at Soul Draw, but they have upped there minimum order, so it may not be economical for you. I'm usually ordering multiple sets at a time so it works for me.
I just use self adhesive vinyl for the sides & control panel. I don't cover the control panel with plexi, so far it's been fine. If this was getting heavy use like in an arcade, then I would.
The ultimate widescreen has been a very good seller lately, but I haven't seen many threads on them. I can tell you it is set up for Sanwa controls, 2 x JLF joysticks, 6 x 24mm OSBN buttons (screw in) and 16 x 30mm OSBN buttons (screw in).
