Which Wavebox? (Or Vortech)

[Canadian]

I haven't read the whole thread but considering you're concerned about noise I thought I would mention:

There's a distinct possibility that regardless of whether you choose a Vortech or Wave Box you may run into the problem of noise from your overflow box surging a bit as the wave height crests over the overflow.

I have a Vortech but haven't used a Wave Box so I can't comment the propensity for creating a surging sound in the overflow. I'm not a huge fan of Tunze in general though considering I've had to replace 3 Tunze 6025s in the last year (and the brackets several times) and over the weekend I just found that one of the magnet holders had a leak in the epoxy coating leading to the magnet swelling and rusting for God only knows how long. At this point I'm confident saying I will never buy another Tunze product.
