I have had a Salsa Deluxe for about a year and I like it. I loved it at first, but then the lock stopped working after 4 months, kind of a bummer for something so expensive to not have a better warranty.
Anyway, it is a nice piece. It is worth noting that the Deluxe has a hair less space than the standard Salsa because of the add-a-bag feature. I don't really use this, and when I have it didn't really work great (pops off with lighter bags). So I'd rather have the space but the other features of the Deluxe are nice.
