My faves are all old. Lyotard 23 touring platforms, Campagnolo C-record Strada Platforms, Campy Chorus Strada Platforms, Shimano 600 EX 6207, Shimano 105, and a few others of similar architecture. The weighting of the Campy and Shimano models are best for easy tip-in. No cleats, slightly snug straps, my foot only falls out when I want it to. The C-records now sell on Ebay for several hundred, but I got them in the early '80s for about $35 the set complete NIB.
