I carry a Micra as a kind of "gentleman's knife" for the scissors and the nail file/nail cleaner mostly, and the eyeglass screwdriver sometimes.
I often carry the Supertool for the saw and file, and the solid lock-up of all the tools. I had a Wave but didn't keep it. Beautiful knife, but ... I don't like tools that don't lock, I don't need tactical opening on a multitool sheepsfoot, etc.
If I were looking for my first, I might go for the Supertool 200, for the easier unlocking, or I might go along with pizzini.at and get a Victorinox. They are just as solid and reliable as the Leatherman line. I really like the simpler, cleaner designs.
I had a Schrade Tough Tool, which was a workhorse, easier to use than a Supertool, with more cutting tools. I didn't need it with my Supertool, but it was too good to waste, so my brother got it
Remember, any of the higher-end -- not necessarily expensive! -- models will be a good buy, so don't worry too much, once you find one that matches your requirements.
