I hear ya Chris, I really don't for see any more major add-on to this tank. I am almost happy with the way it is and the RKE has a lot more that I could add down the road. I just like the simple set-up factor, I have talked to a few people with both APEX and RKE and most say RK is a little easier to set-up and run. As my wife will have to be show how it work to it has to be a little easier.
