I have one of the Romanian AK style SAR-1's. Mine is a 2002 model. I have heard of canted front sights, mine didn't have one. Mine did have a little trigger slap, I replaced the trigger with a Red Star Arms trigger (~$50) and what a difference it made!! This thing is a great shooter now. Notice I didn't say MOA shooter, though. Accuracy is OK, I didn't get it for a MOA gun, I got it for a fun blaster gun. I have never set down and tried mine out for accuracy, but it will hit rocks and clods on the berm at 100 yards+. I would say it is a 4 inch shooter, probably. I haven't had any feeding problems, though. It eats all the Wolf I can put in a stack of 30 round mags, and eats it as fast as I can pull the trigger.
The true SAR-1's take the standard AK style mags, there are also WASR's that are modified to take hi cap mags. Not real sure about the reliability of those, though, as I don't own one. Seems like mine came with a 10 round and 40 round mag. Being that I already had one AK style rifle, I already had a stack of 30 round mags. They can be had for less than $10, though, so mag availability isn't a real issue, as long as you live in a free state. Ammo is cheap, I bought several cases of Wolf 7.62x39 for ~$66/K a year or so ago.
As for reliability, heck, I just shoot it and put it in the safe. I have put several K of ammo down range with mine, maybe I should check it over and see if it needs cleaning. I got mine for around $275. I hear that they are over $300 now. I have also heard rumor of them quitting importing them. If you can get one at a decent price, maybe you should jump on it. It isn't the quality of an AR15, but I didn't pay the price of an AR15, either.
Safe shooting. Here is mine...
