snip My problem is a lot of work done where cords can be an issue or
where
power is not easily available. It's especially true of the circular
saw, I'm tired of cutting roof sheathing with a cord tangled around my
feet.

I wouldn't plan on cutting too much roof sheathing with a cordless. They're
nice for some things, but aren't meant to do severe duty.

When on a job, we always had drill/drivers and usually cordless recipro saws
and circular saws as well. We did new construction and remodeling. We used
the drills the most, then the sawzalls, then circular saws. Although we
probably used the flashlights in the kits more than the circular saws.

But I sympathise with the batteries, I have extras charging all the
time for my drill.

The sawzalls and circular saws both EAT batteries, so always keep one hot.
We usually started out by plugging in the charger first thing on site.
