The Grip is an excellent knife, my favorite is the 550HG.
Really like the hollow ground blade, and just the over-all grind.
154CM is an excellent all-around blade steel (much better then S30V in my opinion) the ergonomics are very good, and the Axis lock is not only solid, but a ton of fun to play with....
The handles (almost everyone's complaint) are solid and have zero issues, but they don't feel as solid as G-10. There is a large aftermarket for Grip handles, so that's an option if you don't like them, but I doubt they will be much of an issue.
I had a set of Micarta handles on one of my Grips from Cuscadi, and it made the knife feel like something that was much more expensive than the sum of it's parts in $.
You really can't go wrong with a Grip, and it's usually under $100.00.
I really like the PM2 as well, just not the steel.
