Well, I don't want to get into a big flaming "war of the experts" here, but my girlfriend and I have one of the new style stainless Mini-14's, and we really like it. I have a Bushnell 3-9x40 scope on it. I have 2 factory 5 round mags and 3 stainless 30/5 round mags that I bought from someone on CGN for $50 each.
The gun will never compete with any bolt action rifle for accuracy, but I have found the accuracy on the "new" models to be much better than I was expecting it to be, and acceptable for the design. The fact that you have this big M1/M14-style bolt that blows back on every round means that you have too much movement in the gun for pinpoint accuracy, but I find the Mini to be acceptable out to 100m. I agree that 200m is a stretch for this gun. We do most of our shooting with it at 25/50/100 metre berms at the range (which is what most of the people I see shoot their AR's, SIG's, etc. at. Hell lots of people shoot their .223 AR at pistol stand-up targets

), and it is fine at those ranges. I have family with farms in Saskatchewan, and I'd love to get it out on the flatlands.
Mine has never jammed, with either factory or aftermarket mags.
I think it's a fine $800 semi-auto varmit-type rifle. I find that most of the #####ing about specific models of guns comes from people being totally unrealistic about the limits of the firearm. this thing was never designed to be a sniper rifle.
This is my girlfriend shooting the Mini. Despite her diminutive stature, she shoots this rifle very well.
