It'* about time I bought one of these things today. I also bought a $10 3M kit along with it so I can erase away gasket material from heads and the block.
I got it at Advance auto for $70. I'm not a fan of Advance, but Autozone didn't have anything.

So far I like the tool. It fits in my hand very well and is easy to "throttle" the air control. That is, until my air-compressor decided to continuously unload itself via the auto unloader.
Another $26 down the drain.

Good thing is, it will be here tomorrow with only $9 shipping. Guess I can't argue that considering how valuable air tools are these days.
