Review on Astro Pneumatic Tool 4980 0.498" Shank Heavy-Duty Air Hammer/Riveter by Threlkeld Drauch

So far so good, although it's stronger than my old air hammer, it's easier to control. A HUGE downside is that it's almost impossible to find bits for it (some say you can use regular .401 bits, but I wouldn't recommend these). Therefore, you have to order them online. I also recommend getting an Astros keyless chuck, which makes bit changing easier.
