Assuming you're going to use it, I'd start with a Pioneer or Tinker (two layer). In the larger 111 mm size, I think the Centurion (two layer) is a good pick as it is basically an over sized Tinker.
If you want something that you might find useful hiking, I'd look at the one-handed Trekker which is a three layer model with the saw blade. I carry the Adventurer which has the side lock and I really like it, but I read that it has been discontinued. Last I saw, a boy scout version still existed which is priced a couple bucks more than the regular Adventurer (probably royalties to BSA).
I would avoid the Alox models to start and go with a traditional Vic SAK to really start to see what it is all about. Then move to the Alox models if they appeal to you
