FWIW, I bought my MK012's from Ken at Recording Services through eBay and was nothing but happy with both the products and service I received. When I first discovered his Oktava auctions, I emailed him about whether he sold true matched pairs, how he tested them, etc. He actually called me at work one day and we talked for 20 minutes about his procedures, his background, his studio, etc...I learned a lot from him in that short period of time, he knows his stuff. I also bought an aluminum flight case which is real sweet for about $45.00.
Hmm, I wasn't overcharged for shipping so I'm not sure what happened with Jason?
Anyway, that's what happened with me, just thought I'd throw it out there...
peace,
Keith
