Ok, I think I have done enough research. I am not trying to get crazy or anything. Just want to keep up a little more. Here is my plan. Please feel free to give recommendations. I will try to add pictures of the pieces and prices. I haven't gotten into the batteries or cables yet. I will probably start researching that soon.
