I HATE Direct-Drive! Why Whirlpool went from solid, powerful belt-drive machines to these boring lightweights is beyond me. On the plus side, they are somewhat reliable and much easier to service.
I used a 1998 Kenmore 80 Series DD machine until last week, when I moved it to the back room and put the 2003 Maytag Dependable Care back in service (still a short stroke, but slower and much more entertaining with the Power-Fin agitator). The Dual-Action agitator makes DD machines much more boring, I used a DD Surgilator on the Kenmore for a while and it was actually quite fun. When I get my "washer shed" finished the Kenmore will be used down there with older machines; it has been very reliable with no problems yet.
KitchenAid has a turquoise Dual-Action agitator with a wider base, and a 3 speed motor. If I am correct, high speed is only used for draining and spinning, and "high speed agitation" is really the medium speed, so it has a slower stroke than Whirlpool or Kenmore on high. No WP/KM DD machine has a slow stroke period. I wish they did, but that's not going to happen.
