As far as flight bags are concerned, you can't get much cheaper than these - and still get good quality. I can't justify paying $300 + for some fancy leather embroidered, whatever bag, at regional pay lol.

Cheaper Sparco Flight Bag

I got the new Travel Pro Crew 8, and am really happy with it. It is supposed to be much improved over the previous Travel Pro models, but the other crew bags mentioned above are good too. I think the Travel Pro might be a little cheaper. Good luck!
