I have the Everki Concept Premium bag (aka expensive as hell bag).

It's a great bag - it's durable, looks great, and has awesome features that work well. You can get a smaller or different bag for under $150 or $100 from Everki, which isn't too much more than the others.

I had a swiss bag before it and the right shoulder strap literally fell apart. It was an okay bag, but just not durable at all and didn't look too professional. I can see the Everki lasting for years and years.
