Nothing wrong with the ILBE packs, especially for the price RatFink mentioned. They are an Arcteryx design, based heavily on the well respected BORA series.
I've used the BORAs for years and never been disappointed. Last year I bought a ILBE and used it while sheep and elk hunting. It is a good pack for the money. Heavier than some, but can be lightened with careful use of a razor blade...
Personally, if spending the money for a MR pack, I wouldn't pick the NICE framed packs. They just seem to be a love them or hate them type of pack, especially as far as fit goes. Fit trumps all, IMO. I own a couple of MRs now, and really like the Grizzly. It fits me very well, feels a lot like a BORA, just a bit more comfortable and well built. Mystery Ranch makes awesome quality packs! As long as you can get proper fit with one, you'd never regret spending the money. Perhaps a NICE would fit you just fine...
