That is the first bag I bought because it was so inexpensive and I wasn't sure what size and features I would eventually want if I were to spend more than $20 or so. I'm still using it and it has held up well, but I paid more for the quad shocks I use to carry it comfortably than I did for the bag.
Though mine has had no durability problems yet, I have read many reviews talking about the poor construction. I have also seen the side pockets blow out on other people's identical bags. I used my bag hard all last year and have begun putting mileage on it again since the weather warmed up. I think the key to keeping them from falling apart is to not load the side pockets very heavily. The blow outs I've seen are on a bag that often did duty carrying beer in the side pockets.
I added a basic cardboard box insert to my main compartment shortly after purchase. I keep the 6-pack or whatever in there next to the discs and the bag shows no signs of failure.
Also, yeah... I would feel kind of ripped off if they came out with a new frame system and it didn't ship with the bag I just ordered.
