While far from the quality of the first party shell, the aftermarket NES shell actually went through a revision and is much improved over the first one - you can differentiate the two if attempting to buy one by the rubber pads that cover the screws, the old version uses shiny silver while the new one uses matte grey. The new one fits better and is got better feeling plastics.
Glad to hear it! I’ll make sure to keep an eye out. I might have to get started sooner than expected haha I’ll try to remember to post when it’s done :)
