Yes, it is really that good and then some. I'm the one who purchased this tuner and I was very happy to get it for that price. It's been completely restored, the MPX/Mono relay coil has been by-passed for significant sonic improvement (I didn't actually think it was possible to improve on the sonics, but Piere at Mapleshade assured me of this and he was right). By comparison, all other tuners run a very distant second to the 4310 in every conceivable way.
