I've seen the ad. The Romaks in the ad have a little better fit and finish overall, and you don't have to deal with the US fire control parts(seem to be soft in the '99 SARs) since these rifles have the "bunghole" stock. I also have not heard of anyone having a problem with a canted sight base or gas block with these rifles either.
There is a guy on AK.47.net(posts as Omar) that bought two of them, and he is working on a step by step tutorial(including pictures) of the steps necessary to add the romanian site base/compensator to these rifles.
The only negative from my perspective is the "bunghole" stock. The pistol grip area is really fat(IMHO). If you like the look of the stock(it is attractive), and you find the grip fat, you can always recontour it to your liking. Or, as others have done, replace enough of the Romanian parts with US, and put on a pistol grip.
