Staples has a leather(ette?) "shirt pocket briefcase" that isn't a Levenger SBP, but it is close enough for people that are on a tighter budget. It is a very clear knock-off of the original, but that may be a good thing for that price bracket.

They don't have one in Balistic nylon either. Boo! Mine is fraying a bit and I'm afraid I'll have to move to the slip-and-slide leather model.

But at Staples under their "M" line or whatever, there was a display at the front of the store when I went. I don't remember the price but it was low double-digits.
