thanks again AZdesertrat, one other thing though is iam in canada and right now my email isent working but will any of the sponsers ship to canada? aquasafe has an office or something here in BC witch i gess is why they dont charge brokage ect for the unit crossing the border witch is a main reason i was going to buy from them, sence haveing another unit shipped over might cost quite a bit in brokage to my understanding and i coudent find another company like aquasafe wich dident charge brokage or at least i could be sure it woudent cost me more than a basic unit localy would you know of any? or if i buy the aquasafe unit could i take off the horizontal DI canasters and add one of the better 10" ones too it after?
