Beat option for blu-ray display/storage

[classicmaterial]

I know there's probably multiple threads that address this but my two Atlantic towers are falling apart (never really were great to begin with) and I'm looking to replace them but everything I find on Amazon has reviews that describe the shelves as flimsy.

Aside from spending $500 on a bookshelf from a furniture store can anyone recommend a good option for a media tower? My collection is ever expanding so I'd say it should hold at least 500 (or be something I can buy multiples of for that purpose)

Any suggestions will be appreciated. Thank you!
