As what *travajante have said, whatever brand you choose, just make sure proper maintenance is done and have an oversized drain. I've seen a few units where an annoying leak is caused by a clogged drain pipe.
my colleague had her pipes buried in the wall.
when it started giving problems,
she had to bakbak the wall.
i have seen some examples, where an aquarium pump-like gadget, would pump the drain water out...
i am wondering, isn't this a design waiting to malfunction?
