well, HD does its thing, but I have often seen new Makita brand 18V chargers online for somewhere between $20 and $30. Batteries also are likely cheaper online than HD. But no matter, around $350 sounds like a good value for that saw and kit if you are not already in the Makita system. I like the saw -well on paper and vid at least, since I have not used it myself-.
But back to the main question, and not to fixate on the 06, I do wonder how long the 18V is going to remain a good option, though. I would think we are likely to move on to higher voltages as batteries get better. Except that the higher voltage batteries are all over the place right now with no standardization in sight.
So, what I'd want to know about is how long the batteries will be available for any cordless tool -like a saw- that I buy today. And, of course, I don't know that. But I do know that I am runnning a 30 year old gas saw, with plenty of parts available today. I also know I don't have any 30 years old cordless tool with batteries still usable or purchasable, though. Now admittedly, I guess many people are not working on a 30 years horizon and are fine with chucking a tool after 5 years and getting a new one, so they may not care.
Either way, we should count our blessings in the US, price wise. I have often seen Makita and Dewalt tools sold in Europe at prices that would send most of us into shock-induced coma...
