The harbor freight pneumatic riveter works great. It is under $40 on sale. I pulled close to 10,000 rivets with on one my Sonex and it is still going strong. Any compressor, even a mini pancake one will run it. A hand riveter will work in a pinch or in tight places but it was always much harder for me to get the rivet to sit flush and fully pulled using a hand riveter. There is a tendency to put twist or angle into the hand riveter and not keep it perpendicular to the surface when trying to squeeze the lever.
