I suggested this one to another person with the same model BVM. Questions on the item suggests it will hold at least 250lb. That doesn't sound wrong to me. If you fully load this up with audio rack gear, you'll hit 200lbs easy.

If you want cheap and all metal, try this one. Not sure on weight handling, but it looks sturdy enough. Some buyers are claiming the screws and threads are wonky. Looking at the pictures, it's probably because it includes 5mm (#8x32 audio rack standard?) and 6mm (M6/ HP Server rack standard) screws and an extra set of threaded rails for those. And the instructions probably don't explain or label that at all.

If money is no object, the Mid-Atlantic racks are actual pro gear.

You could, of course, build or modify your own. There's a few sites out there that explain all the finer points. (Pro tip: don't start with a cart or table with round legs. Thank me later.)

You can also get casters for anything under the sun. SES Caster Company (Stanley E. Smith) sells through Amazon and has great customer service. I bought a set of their food prep table casters for a rack I'm building. I'm STILL waiting for some saddle spacers to help mount things straight on round legs, so that's on hold till then.)

Finally, check [public service auctions](www.publicsurplus.com) near you, and maybe you can score a heavy duty TV cart or rack for cheap.
