I just purchase 2 Mackie Padded Speaker gig bags for my EVsx100's at the Guitar Center. They were used, however they look like they were never used. Normal price is about $70. I got them for $39. They are heavy duty woven ballistic nylon, with padding, plenty of room for the speakers, zippered compartments for the chords, opening for the handle almost lines up perfectly, and a handle on the top of the case, for convenience. The only thing missing were the shoulder straps, which I would never use anyway. I got the EV's on close-out, and now the gig bags very cheap.
There are bargains out there, you just have to be lucky enough to be at the right place at the right time.
