Welcome to our forum.
We passed over the Beachcomber during our search due to the external pump. The additional space required just wouldn't work in our location. Make sure you take the extra space into account!
SJK,Beachcomber uses a BIG circulating pump to filter the water and Sundance uses a little one with pump 1 coming on low every so often (this is programmable) to help filter the water. I don't know if the circ pump is an option in Beachcomber or it's standard.Every manufacturer tackles filtration differently and none of the major manufacturers have a problem keeping the water clean. Don't let this be a deciding factor in selecting your tub.
What about the turbo option? Its an extra $350.00, but I've been told its "a guy thing" - not really that useful. I'm almost sold on the 720.
I will go one step further with this. In my (measley) three years in the business, I have yet to encounter anyone, I repeat, anyone who has complained of inferior filtration systems. This includes a variety of tubs purchased at big box stores.Filtration just isn't an issue within the industry - at least in my neck of the woods.
