I'm looking for a wallet to give as a gift to a fellow who overstuffs them and thus burns through wallets pretty quickly. Durability is more important than looks, but it's for a white-collar professional type; I'm trying to steer clear of anything that looks too unique. Any suggestions?

I'm also taking suggestions for wallets that are an outstanding value; if I can't find a really rugged one, I'll just get him three run-of-the-mills, I think...
