I bought from casesforcollectibles.com. Go to their site, then look under Acrylic Display Boxes (the top left product type) - they have a price calculator where you put in the dimensions of the case you want and options you choose like a mirrored back, etc. and get a price and can order it. Took about ten days: they actually custom build it for you. I got a simple clear case with black base, 34 x 7 x 7 to display my third rail 2900 Northern for $105. Very nice case.
