I finally ended up building mine from MDF. I don't like storing albums in a way that I have to read the spine to find an LP. I like to flip thru them and see the cover. I started out with one design but as I built it, it morphed into something else. It was suppose to be simple and cheap, but turned out costing a little shy of $200. It fits most of my 1200 LPs but I still have about a 100 that did not fit. Since I built it in a closet, there is no more room to make it bigger, but I am satisfied since the LPs are no longer strewn all over laying against the walls. It was a *lot* of work, so make sure you are prepared if you decide to do this. Good luck on your search.
