Go to theelectricbrewery.com and read his instructions three times over until you understand how his system works inside and out.
And THEN decide if you really do want a simple control panel or if you want something more and the only reason that you said that you wanted something simple was because you were intimidated by the seemingly complex control panel setups.
Agreed. I also suggest that if you do end up building a panel that you leave extra room for expansion. I bought Kal's back to back kit (HIGHLY recommended BTW) and have already modified it twice to add extra functionality. It's really hard to know everything you need until you actually put it into practice.
Also, you are talking about some pretty serious current here. Sparky can and will kill you if you do something stupid. Don't rule out buying a pre built solution. Kal's panels are very reasonably priced, especially when you take specialty tools (and labor) needed to complete them into account, and they are definitely cheaper than the average funeral.
There are also the BCS panels if you want to go that way. They are available assembled here
