Somebody on AudioKarma liked it best of all the carts that eBay seller is selling. Appears to be a standard elliptical bonded but we shall see. Yes, it's an older style Audio Technica P mount body. I'll have enough carts for an army of turntables. Listening to the AT450 on the Sony PS-LX520 in my living room and I'm really impressed. This one sounds better than the one I put on the Technics upstairs, but it could just be a better match for that turntable. These are universal mount I think they would better most carts out there under $100 for a standard mount.
