I put outlets everywhere I could and recommend it as you will change your configuration so many times. Put them on the walls at about waist height that way you don't have to crawl on your belly like a reptile to plug something in. I have them on the bottom of the trusses to run my lighting and drop down in the center areas of the shop. Panel should allow for 220 expansion as you wil probably want a large compressor/ mig at some point. Simply put, you can't have enough power! Watch your security and use good locks(medco) and doors without windows. I have 3 windows on the front to match the home cosmetic wise, put some higher end security window tint/film on them...resist smashing and keeps eyes from seeing in. Reduces heat from the summer sun as well. Hope this helps ya!
