I have a couple of Artisan and Artist bags (ACAM-7100) which I paid about $149/$179 when I bought them. Folks thought they were overpriced then and probably still do since they are priced at $319.00 at one of the sponsors web site currently.
When I look at this bag (Ghurka), I find it is not functional for the gear I would carry. If it was a functional bag the price tag would be prohibitive. I look at the price of this bag as some looked at the price for the AA bag that I love and thought the price was worth the value of the bag.
Different strokes for different folks.
As a side note, I have a leather soft briefcase that I bought in 1988 that I still carry today. Back then I paid a few hundred dollars for it but it still is fully functional today. Some times the extra dollars spent turn out to be a good investment.
