As tommy has stated Innovative runs a great one on in Jacobus, Pa. Its an incredible class taught by John Jameson, Mike Luongo, and Mo Pinel and, IMO, the best bang for your buck. What you learn in the class opens more opportunities than any other class, as Mo wrote a lot of the information for the other drilling classes so why not pay to hear it from the man himself.
Aside from that, a free lesson from Mo, a $300 credit towards innovative products, and the opportunity to drill using cutting edge equipment.
