What is a good store to buy quality display cabinets?

[BioBrick]

So I've been collecting Lego over many years and I've come across an unsuspecting foe: DUST!

I want to buy a nice display cabinet or shelf to showcase my collection while simultaneously keeping it dust free.

Does anyone have a store recommendation on where to buy/order something like this? I'd like one located in the U.S. so I don't have to deal with international tape.

It must have a glass door(s), preferably a sliding one. A lock would also be nice as neighbors sometimes bring their kids over. Rearrangeable shelves would also be a plus as my models come in all sorts of different shapes and sizes.

My collection is quite large (every Star Wars and LotR set ever released) so I'd need a large unit, or at least a decent sized one that I can order multiples of. I want to keep it under $3000 U.S.

For dimension considerations, the largest models I have are 50 in long, 16 in wide, and 26 in high (these 3 measurements are from separate models; not the same one).

Any help would be greatly appreciated!

Give Ikea a look.

Agreed, IKEA is probably your best bet - but Raw Wood Furniture, or something like that, can also be a possibility, if you are willing to assemble and stain/paint your own units.
