I reviewed my options on larger relay sets and picked the following ones from Yourduino site.

8 - relay board-2

4-relay board

I went with the Opto-Isolated units as they are much safer when using around water and 120 volt systems.  My plan is to build a 12 outlet controller portable unit. Don’t know what it will look as yet because the plan is still in mind I know I will have 8 relays configured to be in the closed mode and the other 4 relays will be in the open mode.  This I think will give me the most flexibility with all the items I want to control with this unit.
