@noromance: Loudon! A favorite of mine.
I can’t post pics, but can safely recommend the EKET rack from (what else? ;-) Ikea. I have fifteen of the 4-cubicle EKET, stacked three high and five wide, each EKET secured to the one above and/or below it (Ikea offers a kit of parts for doing so). The total assembly (with optional but recommended feet) measures 7’2" tall by 11’6" wide, with sixty (15 x 4) 12-3/4" cubicles. Each cubicle is also 12-3/4" tall, just barely enough for jacketed-LP’s (which is fine with me. Less ability of dust to accumulate on them ;-) . The cubicles are 13" deep, which I prefer to the excessive (imo) depth of the Kallax---which also suffers (again, imo) from an open backside (come on in dust!). Each 4-cubicle EKET sells for $65 in white, $75 in blonde, light grey, and charcoal. The charcoal sold for $50 when I bought mine a few years ago, imo a great value.
I compared the EKET to Ikea’s slightly cheaper Kallax, and went with the former. More structurally sound; there are numerous accounts of Kallaxes collapsing under the significant weight of LP’s, but I have not seen a single report of an EKET collapsing. Some have added bracing to the back of the Kallax, which I would strongly suggest (as well as a back panel to keep out dust). Or running them from side wall to side wall, so that collapse is impossible. My EKET stacks are absolutely unmovable, feeling like they are a part of the room’s structure. I just hope my floor doesn’t collapse!
