The Yamaha T-1 is the one I have. If you want the best possible tuner buy under $100 this may be the one you should have too. It is not a super-tuner, nor could be at the price, but it is astonishingly musical.
I also like Rich's suggestion, above, that you consider a receiver from the seventies. It is true that some of them had excellent tuners. Luxman, Sherwood, Marantz, Harman Kardon come to mind, but the Sherwood may be the best suggestion for the price you want to pay. Sherwood was renowned for its tube units in the sixties, and the tuner sections were the best part of their later receivers.
