I took the low road and bought an Irwin tool bag. It is large, has two compartments, two outside velcroed pouches, three outside small pouches, three inside small pouches (battery holders) comes with two suitcase style handles and a large over-the-shoulder strap. I get the 722, two sets of mic cables, four batteries, a set of mics, the Shure A27 mic holder with the Shure A58(?) mic clips, a set of SONY MDR-V6 headphones, and miscellaneous small stuff into it with ease. It is normally $30, and it was on sale for $20. I do not think it is too waterproof, but then I do not take these mics out into the rain. I do not tape in the rain. I do not stand in the rain. It is not very taper-hip, but it solved the problem for me and very cheaply.
As usual, YMMV.
