I own several hammers - some more expensive and better than others but they will all drive a nail.
When I decided to get my rPAL and buy "something" my internet research lead me to look at what was available and check the reviews. The Girsan MC28 gets pretty good reviews and it was considerably less expensive than other options. So here's the way I approach a new sport or hobby; buy a functional but relatively inexpensive version of whatever the thing is and try it out. If I decided to learn to play the guitar I wouldn't buy a professional level guitar but a basic model. Maybe I don't like playing the guitar, maybe I drop it or mess it up somehow. I know that eventually, if I stick with it, I'll upgrade to a better guitar and when I do I'll have a better I idea of what's important to me. So it goes with this hobby. I have since purchased a much better pistol, lighter, less recoil, better trigger, red dot (for more than 5 times the price of the Girsan). I still have the Girsan. Do I regret buying it? Not in the least. Taught me a lot about the effect of different backstraps on my grip, learned how to be accurate with a trigger that requires a longer pull, learned about how to place my finger on the trigger.
I learned to drive stick on an old beat up Toyota, could have saved my money until I could afford a Corvette I guess but that old Corolla taught me a lot.
