I tend to not stick to the one brand.
The best thing to do is to go and talk to the sales team at a few good tool stores (Specialists stores not Bunnings).
Ask the blokes there.
i had one of the last black & Decker commercial cordless drills they made b4 being bought out by Dewalt, $200. Lasted 6 years ( I'm a shopfitter/Carpenter) used the thing every day, even had a holster on my tool belt for it. Replaced it with a Metabo $500+ and have had no end of trouble. So you see it doesn't matter who is more expensive or more colourful, each company specialises.
i now have a Panasonic cordless, Absolutley brilliant.
As for the cordless action.
I hear "Lead rage" etc etc. All you have to do is learn to roll your leads properly and get a power board.
i have two 30m leads a power board, and a number of short leads2-5m. Why do i not bother going fully cordless?
Well, have you ever gone to site, with all your cordless gear, only to find out that none of the batteries are charged?
Or start work and you use all the battery power up by smoko?
the truth is that all of these cordless saws etc suck the juice out of your battery very quickly, which then forces you to resort to leads etc, or i'f you don't have power you waste a day.
How do i know this?
have attempted to renovate a house with a full set of cordless Dewalt (Friends set). Wasted so much time it's not funny.
anyway thats my two bits
