Hey Doc! I think I can be of help - I own 2,700 CD’s or so right now, so I feel your pain!
There is a very expensive place that does ornate shelving that will grow as your collection grows. Unfortunately, this costs many hundreds - and for the really nice stuff, upwards into the thousands - of dolars to get.
I have a catalog I will NOT be using any time soon that I could pop in the mail to you.
I am not particularly wealthy, Doc. So my (current) favorite storage method might be below you. But here goes…
Target sells a CD shelving unit (technically a “Multimedia Storage Tower”) manufactured by Sauder. Target sells them exclusively, in fact. (Model # 9029-290)
You put it together yourself with a hammer and phillips head. It is pretty sturdy, looks nice (choose black or wood) and holds 532 CD’s.
Best news - Only $44.95 each!
I have two of them now, one of those dowell-rod shelves that holds about the same but is taller and not as sturdy (but I got it used for only $25), and the rest is in my old stand-by, milk crates!
Those are REAL CHEAP! But I’m glad to have found something that ain’t too expensive but holds a LOT of discs!
