I can't speak for the newer ones, but the fit and finish on the SLR-96 I'd picked up a couple months ago is superb.
I would say to check condition. I run across too many AK derivatives that are, well, used as the AK was meant to be used, out in harsh conditions (like hunting with it on the back of an ATV, in the rain) with little or no maintenance. It will keep shooting forever, but that does ruin the finish and it might even have rust. Also, some people will use corrosive surplus ammo and not bother to ever clean the gun, and it could even have rust in the gas system as a result of that. So check condition thoroughly, don't buy sight unseen.
That's my only advice. The Arsenals are beautifully made, at least my older one is. I paid $525 for it in pristine, likely unfired condition, and every part was perfect, from the parts fit to the crisp and smooth double-hook trigger. I also believe that price was well below what they usually go for!
Don't forget mags! Beware of the orange ones that people have bubba'ed with a dremel to badly feed 5.56x45 variants. They won't work well for that, and they won't work right for 5.45 again either. I believe Bulgarian Waffles with the steel reinforced lips are the best made in that caliber. You can get them from K-VAR.
