The brand that I love (I have three luggage pieces and a computer case) is
Briggs and Riley.
THe link below will display a case with the characteristics you are looking for (the rest of the line can be seen as well):

Nylon is displayed, leather is also available.
I think that B&R is Tumi's equal in quality. Both brands come with lifetime guarantees including airline-caused damage. B&R is usually available at a "kinder and gentler" price
Disclaimer: I have no connection with B&R except as a extremely satisfied customer (and I'd never even heard of the brand until I first started reading FT 4 years ago).
