I purchased mine in September of 2002. I am just as pleased with it today as I was four years ago. The quality of this bag is superb. I agree with other reviewers in that the amount of stuff you can put in this bag exceeds your first expectations. I have put in it the following: Canon 20D, Canon 5D, 50mm, 16-35mm, 28-70mm, 70-200mm IS plus Flash (EX550), filters and other incidentals. Yes, it was packed and no, it was not easy to use with this much stuff in it...but it worked. I am impressed with the strap - the amount of padding and the overall construction is excellent.
The bag is heavier than others of this size - but it provides more protection than other bags. And the bag can get quite heavy due to the amount of equipment you can put in it. But then again, these aren't really negative comments.
