Got a Snark, original Polytune and a Turbo Tuner and all 3 are good. The TT tracks the quickest and seems the most accurate but the Poly is pretty good but in single note mode, I don't find the Poly mode very consistent. I had a Strobo stomp for quite a while and loved it until the switch started popping, I got real used to the display and liked it a lot but the pedal size was a little big. I gave it to a mate a couple of years ago and whilst it still pops, it's still going strong. These days it's the TT all the way, small and compact, very well built and robust, excellent display under the lights and in daylight and damn accurate, one thing though.... no power out to connect more pedals, you'll need another power source for those!
