I got one of these, for 90 bucks, and I tell ya, it's almost every bit the bag the Mono is.

Ibanez idbb5. It is an EXCELLENT bag. I've had mine just over a month, and thru all my gigs it has been excellent. It stands up on its own, has neck retainer straps, two huge pockets at the bottom for charts, cables, etc. And a top pocket for other accessories. Robust padding, casters, front stand, and not butt heavy. Good lining material, great heavy zippers, and a tuck-away back-pack style strap system. Very good quality luggage-style construction.
Just another option
And as suggested, I did in fact scotchguard it. funny.
