i know you already found one, just wanted to put in my $.02. i use this guy
http://www.djdeals.com/procasesPDJB.htmfound it at guitar center (not the version shown here with the wheels (but i wish i had found that!) but the same thing carried like a courier bag) for about $60. my rig is pretty big though with a laptop and formerly a m-100fx, but now with a UA-5 its a little better. this things a beast though. lappy, batteries, UA-5, cables, and mics (in cases) in the main compartment. then headphones, duct tape, various other cables, wallyworld bat, sbd patch cables, and other shit in side pockets. nice little hiding places in the lid. i love this thing and highly recommend to anyone who needs a case. made for DJs to hold LPs but its big and padded and kicks ass.
