Keith's has about the best selection of AK's in stock...ranging from WASR's to ARSENAL products to VEPR's.
As for customer service, while it's true that you do run into some different personalities there from time to time, even from the same folks, you can find that just about anywhere.
I've done business with him for a few years now and have purchased most of my firearms, accessories and ammo from him. As far as customer service, I usually get treated okay there, sometimes smiles all around from the whole staff. But there are those 'off' days,...and not coming to his rescue or anything. We all have them.
But if you go in there with your head on straight and any attitudes in check, you usually get treated the same and with respect in return.
As for the AK's, he does have the selection and enough stock to see and feel the difference between the low and high end models. It is an eye opener to put a WASR (the replacement for the SAR's) next to an ARSENAL or VEPR. But then again I have seen some SAR's and WASR's cleaned up with refinished stocks, sights, grips, etc...and still come in for quite a few pennies less than those cadillacs of AK's.
So it's all in how much the bank can handle and what you are looking for in an AK. But in the Portland area (Gresham in Keith's case), that is where I would start looking first.
