Davey, if you can scrape up the coin I'd go ahead and run some drops for the compressed air as well. That's one thing I didn't do in my shop and now very much wish I had. I don't want to add the piping over the painted walls and I find that only having one source for air is sometimes inconvenient as I'm having to drag hoses around the shop and also do a quick change with air tools instead of being able to use two hoses with different tools attached.
