I really like mine. It's got a nice "boom" factor, and the round it fires is readily commercially available (from Winchester and S&B). It's a single action, with a cool mechanism borrowed from, or similar to some early German full auto. I liked the mechamism since it's not just another tilting barrel. Extremely well made and sturdy, sort of how I would expect a Czech military weapon would be.
I don't know about the gun shooting low. I tend to shoot mine high and to the left (about 10:30), and I'm trying to figure out if it's me or the gun. I suspect me. Most people I've read say it's a "tack driver", maybe partly due to the non-tilting barrel. Some have reported that it "points low".
There is a fair amount of information at makarov.com, if you follow the CZ-52 link off of the main page.
There is some much hotter Czech military surplus ammo around (I think I've hear 1900 fps from people that have it). I've never fired that. The S&B and the Winchester standard load clock in at close to 1650 fps, which is moving along (for a handgun). Probably too much penetration for most self-defense purposes, from what I've heard.
I paid $165 for mine, which was in NRA Excellent (confirmed by the gunsmith to whom I had it shipped- I don't know much about those things). It looked unused, except for holster wear. The gunsmith said he wasn't sure the gun had ever been fired, and the bore was in perfect shape. I think that $125 would be a fine price for one in NRA Very Good shape. Prices, in general seem to be going up.
At any rate, I like mine a lot. I decided to see how much an action job could improve the trigger, so I sent it off to "Actions By T".
I can't know if it's worth $125 to you, it was certainly worhth $165 to me.
