You've found a "good" quality AK, if you've found ARS. I've got three of Marks builds and absolutely love'em, I don't have pictures but there is a picture of me with my favorite one on this website (up at the top) from a training class I took with LMS:

I bought this one in Dec. of 07 and have about 3,000rnds. through it, another two hundred or so tomorrow (shooting a match) and I've got zero issues with this rifle. More importantly I find it to be "deadly" accurate, and the quality is awesome, especially for under 600.00 delivered. I'd choose an ARS (Rom) over a bulgarian for steel hardness alone, ARS also stands in front of there products (just sounds better than "standing" behind). You'll be happy with your ARS AK!
Let me know if you have any specific questions. Hope this helps!
