Give these a try if you are looking for pots. I have not personally used these but we have some similar ones that came with our post frame machine. http://www.autobodytoolmart.com/champ-floor-anchor-pot-1600-p-11538.aspx
We have one that is very similar to that one. I find it very usefull since you can move the seat up and down to different levels. It gives you a better height than just the rolling shop stool.
Another thing to keep in mind is what do you have to store? In my case I have to "share" my 2 car garage with my wifes car, kids bikes and toys. Think about what area you want to be yours and find a space to build storage for all the stuff the rest of the family needs. This will keep them out...
I am a big fan of the Ridgid line of cordless tools. I have a 14.4 and an 18 drill and dont regret buying either. These have a lifetime warranty from Home Depot, even on the batteries.
Very nice build. How many can lights did you install? Did you use a program to determine how to place them or just estimate what you needed? What watt bulb are you going to install in them? I have kicked around the idea of putting them in my shop and really like the looks of them in yours.
I like it. What is your floor layout going to be? What will you be using the room you have studded out in the back for? What ceiling height do you have? This is similar to the size that I would like to build. Hope I did not ask too many questions.
