My job has me editing highlights of sports about some 40+ clips ranging from 2-5 minutes each (depending on play) Since i have to go through all the clips i hate scrubbing with my mouse. It keeps falling off the desk. So i was thinking of getting a job wheel. I see there really is one brand the contour shuttle pro or the express. Does anyone have any of these? Would you recommend them? Are they large as i don't have a ton of space on my desk?
