We have a Samsung 7.5kg toploader and I love it. It has the safety childlock on it as well.

Not quite gettting the whole "things get tangled without an agitator" ....I always had the reverse problem. I find that the not having the agitator gives you more room for towels, quilts, blankets etc. Also strappy things don't get caught up around the agitator. The whole idea of not having an agitator is so the wash is more gentle on your clothes. No, not just you Netix.
