Buy an Oehler thats what many manufactures use. They are the most accurate with 3 sky screens. The model 35 with 3 sky screens($225) is the way to go but you really dont need the printer as it remembers the last 20 shots. Also if you accidently shoot it (trust me it can happen) the replacement parts are available and reasonable. My shooting buddy owns one and absolutely loves it. I am saving up for one now.http://www.oehler-research.com/
