I had a thread like this a couple of months ago!! We ended up getting a dishlex, price was important to us and it had the best reveiw of the cheaper ones on the choice website. I paid the $22 for the reveiws because I thought, well spending $22 on a reveiw and getting one that saves me $$ in the long run was worth it. The child lock on the one we got was the most effective one and Em has only just learned how to press the power button (it is harder to press than the cycle ones) but if she switches it off when we switch it back on it continues the cycle from where it left off. Neither of the girls have figured out the child lock.
