Snare carrier

[playinpearls]

I'm trying to create a mobile computer desk for work and was wondering if anyone has an old snare carrier they'd be willing to donate. condition doesn't really matter, it will be for a prototype before I spend real money on a comfortable one...

Any tips on finding one other than the obvious?

I'm thinking it needs to be one with the two half inch bars that come out...not the single center mount.
