We just redid our hardwood floors and it is a rewarding experience. Be prepared however for a full weekend of work before you can begin the finishing process. Varathane makes a square sander that won't gouge your wood and is made for amatuers (like myself). I recommend the entire Varathane product line and it can be found at Home Depot or Lowe's. The toughest part is the staining and making sure you get it even and don't leave lap marks. Its worth the time and effort though, Good luck.
