Washing machine - agitator vs no agitator

Cassondra09

We have been looking at possibly purchasing another washer/dryer set as we are envisioning ours to poop out any time now. I have read the occasional difficulties that HE washers can have, but what about agitator (the little tube thing in the middle of the washer) vs no agitator washing machines. The no agistator washers use less water in addition to being HE... potential problem? Any experience with no agitators?
