My Personna injector (the swoopy-looking stainless steel and plastic job from the '70s) shaves me very well indeed. I'm still getting used to it, but I like it more every time I shave with it. I wish it were a touch heavier, but otherwise it's a fine, well-made razor. I should get around to writing something up for the reviews section; I'm a little surprised that no one else has, either, at least none that I've found.
EDIT: The best part about injectors in my mind is that they make the transition to wetshaving almost painless: you just have to watch your pressure, but they otherwise behave much like cartridge razors do. If I could start this whole wetshaving journey over, I'd start with an injector.
Funny thing I remember: my dad shaved with an electric, but my mom used an L1. I had forgotten about that completely until I joined B&B and realized what her razor was.
But yes, I think they're the easiest possible transition tool, and good shavers for just about anyone. The DE razor has greater cachet so most go straight to that, though.
