I used to work for a very large bottled water company. Those 5 gal carboys will work fine. You would have to leave your beer in one for many, many, MANY months before you would see any oxidization.
Do you know the rating of the bottles you worked with? Most of the water bottles I've bought are the ones with a "3" in the triangle. Sparklet's is the only one I've seen that has "7"s. Thanks.

Had any problems with the star San yet? That stuff will eat through plastic long enough if left to sit. Probably depends on the type though, because the concentrate is stored in a plastic container and seems to be fine.
The eight or so months I've been brewing, I've kept pre-mixed starsan in a 1gal arrowhead bottle and there's no sign of deterioration. I would assume that the first sign would be hazyness on the inside, but there's nothing.
