Hey all. I'm actually not a musician but found myself in need of a very specific music-related piece of equipment. I have a tripod and need a shelf-type tray to clamp on to the main rod, of the kind seen here: http://www.quiklok.com/catalog/?p=pr...7&sName=MS-329 This company (quik lok) has some but none are the right size, etc. I'm not sure where to look for these online, and was wondering where you'd recommend or which specific products you know of that might fit the bill. Thanks a lot for your help!
