Frankly the bestest scissor switch keyboard for my likings is the one present on the Thinkpad edges, and in the thinkpad X100e and 120e, if built by NMB is just perfect, if built by chicony is very very good.
But is not available as a standalone board.
Logitech illuminated is very close to it although the longer travel, which is somewhere in the middle between a full travel board and a classic scissors one.
Personally I care more of the definite tactile feedback than the travel length, and obviously you may have different likings/needs/priorities.
