Looks good, Arcade.
I purchased a lightbox from River City on Ebay, and had some issues. The first being it did not work when I plugged it in. The second being the guy would not give me a refund, and I had to file a claim with Ebay. He did say that he would send me a ballast for free, and $100 worth of posters, but if I wanted to build a lightbox, I would not have bought one that was already assembled from him in the first place. He said that he would have to charge me a $100 re-stocking fee, so I filed a claim under the Buyer Protection Program which basically states that if the item is defective or faulty, the buyer is entitled to a full refund (without a $100 re-stocking fee). The third issue was that there was paint in the grooves where the poster slides into, a thick coat of paint that was brushed on, or just sprayed too thick, and even if it had worked, I would not have felt good putting anything in there resting against paint like that (especially an Avatar lenticular). The boxes he has that are not the painted black kind would possibly not have that issue, and looking back on it, they do look nicer for a little more $.
I still had to pay $70 or $80 bucks to ship it back, and had a huge, dirty box sitting in my kitchen for a couple weeks. The lightbox didn't have a switch either, so you would have to hook it up to an outlet that is controlled by a wall switch, or plug it in and unplug it all the time. Lastly, I'm not sure about the acrylic between the poster and the lights, but the acrylic on the outside was not UV protective. Other than that, it was a pretty nice lightbox.
