Go's are great mills for the price. I ran a 3port at the IL indoor champs this weekend and won my main. However, if this is your first nitro make sure you have someone that can tune a Go. They are a bit different beast. If you break it in nice and treat it well it WILL return the favor. You can get 7 or 9 gallons out of them and new p/s/r are only $69!
