I plan on using a little tax refund money to buy a power rack and bench for my garage. Any advice on certain brands to look for or stay away from? I'm not against buying new, but I'd rather find a deal used on craigslist. Also, is it easier to do deadlifts on a separate platform outside the rack? What is the best flooring or padding to put under the rack? I'd like to keep from cracking the concrete floor.
