build your shop around what you are going to want to make. then select your extras with usage in mind, I have a shop with three lathes, bandsaw,tablesaw,beltsander,drill press,scrollsaw and lots of space for storage for wood, paint and stain area, woodburning and carving area ..... and still go goo-goo over tools in catalogues and retail stores....it's just a bug you won't get rid of.....good luck
