I just got a Scott case. I expect it to last the rest of my career. Very high quality. And made right here in the US.

I also have a roll aboard bag from www.purdyneatthings.com. And the attachable duffel bag.

Food cooler bag from e-bags. Bring your own food. Ice packs for a buck or two from Walgreens. You will save the cost of the bag each trip if you bring your own food. No joke.
