I bought an $80 'shooter grade' M48A from AIM a while back. It is what it is and I'm more than satisfied for that price (I'd rate it as 'good' condition). It does have matching #s (receiver, bolt, floorplate, and stock) but no cleaning rod or front sight hood. Have never personally dealt with KY Imports but at that price you should be getting a really nice piece. I've examined one from Mitchell Mauser and it did appear to be in as-issue condition. I just think you pay a premium for the hype.
Since I got my C&R, I've found that you often have to 'pay your money and take your chances' when purchasing sight unseen. I have only had to send one gun back that clearly did not live up to advertised condition though a couple have been borderline. The one I sent back (to Southern Ohio Gun) was replaced with a really nice one. Be sure to ask whoever about their return policy (return shipping, restocking fees, etc.) if your 'just not happy with it!'
