The Mini-14 is a great gun.
But you came to an AR-15 site to ask about it. Of course people are going to crap all over it. That's like going to a Mustang board to ask if you should buy a Camaro.
The mini-14 is a great gun, and an excellent value for its money. It's not a tack driver, but if you want a tack driver, then buy a bolt action. It doesn't have the aftermarket support, and a ton of high-speed low-drag goodies to bolt onto it, but it doesn't need one. And if you have the $$ to be spending on all those goodies, then you should just be buying a higher end gun out of the box.
I own a Mini-14, and it's a hell of a lot of fun, it's reliable, and it will shoot better than most people need. It will kill prarie-dogs and gophers all day long. And it's a classy looking gun that doesn't freak the sheeple out the way an AR15 does. It's also an EXCELLENT choice for people who live in locations where they can't have an AR.
