Nothing wrong with one, and $95 (over AIM's price) to cover their shipping, fees, and a bit of mark-up isn't outrageous.
Go play with it a bit in the store. Specifically, extend the wire stock and mount the gun in a firing stance. Is that wire stock comfortable for you? Can you get a decent cheek weld? Does your eye line up reasonably well with the sights that way?
AMD-65s represent some compromises to make them more convienient for troops who'd carry them a lot, in and out of vehicles, tanks, etc., and shoot them a little. If those compromises make the gun less "shootable" for you, look into a different AK variant.
Also, due to the unique kind of receiver and stock the AMD uses, there are no other stocks that will swap in place of it. If you get that gun, you're stuck with that configuration. If your body type works well with that stock, go for it.
If you think it might be a bit uncomfortable ... it will be.
