The Zastava mpap70 w/ the maple furniture is a great "value" AK. It's all in the details of the parts too.
That "guide" mentions the obvious receiver and heavy barrel differences, but completely ignores the machined front sight block and gas block. They're not the typical cast pats that are pinned in place, they're milled from billet and are way more sturdy, with a better front sight system. They also have the X/Y receiver stampings and some nice rivits. Mine ran like a sewing machine, and with a different front brake in place of the stock slant cut, handled fast follow up shots while on the move just fine.
My only gripe is they include a milled front sling clip, and no way to attach one in the rear of the maple stock w/ integrated rubber pad. No sling loop is screwed into the stock. Also can't take off the grip and use an echo-one-nine single point clip because of the riveted trigger guard..... Arrrrrgh.
