Hi, So I'm thinking of clearing a bigger space for training. I don't think it's healthy to spend too much time on cold, hard tile barefoot, and I prefer not to practice in shoes, so I'm thinking about getting some kind of mats. I don't want to break the bank or anything and it does need to be something I can take up and store if I need to. I was thinking puzzle mats, but I don't know much about selecting them. Here are two options I found: Home Sport and Play, $7.56 per 2'x2' square http://www.greatmats.com/products/home-sport-play.php Home MMA Mats, $9.16 per 2'x2' square http://www.greatmats.com/products/home-grappling-mats.php For a 4'x8'space, that's 8 pieces. With shipping it would be about $100 total. Hmm, so that means I gotta save up first if I go that route. Is there a cheaper option for something to put down? Or does it look like these products might not as nice as they sound?
