I really don't have a lot of interest in introducing a new brand of tools, new batteries, and chargers at this point
I absolutely understand that.
I do keep my air gun around the house, but slapping on a battery and removing anything I need is sweet.
The hardest part would be deciding which platform.
DeWalt has more going for it, Milwaukee is solid and built well.
I went with DeWalt for the cutoff tool ( insane power) reciprocating saw, circular saw, ratchet, 1/4, 3/8, and 1/2" impact.
I do have the M12 1/4" ratchet and the M12 hatchet (limb saw) which also has a ton of power, very impressed.
The new DCF891 DeWalt 3/8 mid torque is a beast, that with the DCF900 cover most bases. I would do the DCF900 and a smaller 3/8 mid torque as the 891 is so good ot tends to overlap some of the DCF900's capabilities...so a pricey endeavor.
I gave up on the cheap stuff, wait for sales.
