Probably not necessary, since a person climbing in trees with a saw is
going to have a low duty cycle. It's only necessary to have a tank large
enough to get you through each cut. (And a hose large enough to deliver
21 CFM.)

The compressor is big enough, but my wallet isn't. $2100 for one of these.

I'm buying a $375 version from MSC. If it don't work out, I'll have another
shop toy.
