Having a home gym is worth it's weight in gold (and iron). No driving time, no waiting, no idiots, and all the freedom you need. My advice for the feature machine in your home gym is a high end smith machine that has cage bars, and a lat/row/pull-up bar all in one! Having no spotter the smith is essential. I have a para body machine myself. The only other thing you need besides a adjustable bench and weights is dumbells. I use plated so i can make 20' and up to 100's. Best investment I have ever made. FYI so many people never use their gym so Craigslist is a gold mine to acquire DB, benches, barbells and free weights. In the USA that is.
