I have the rockwall but it is about 5-6 years old and I wish I didnt buy it. It is basically to large for my hand especially with that safety button on the side. It seems it was made for left handed use and I am right handed. I will take pictures later today to show what I mean.
There are corded and battery versions that do do much the same work. I have an older Dewalt 18 V compact DW 936 circ saw with a 5 3/8 " blade if I recall, and it's my "go to" saw for almost all utility grade cuts.
Battery powered saws are so handy that I use them almost exclusively now. My other battery powered saws are a Milwaukee 6.5" and a Rigid 6.5". For down sizing a 4 X 8 sheet of plywood it's great not to deal with a cord. Other use is sawing a gentle curve across the tops of 10 ft long fence sections ... no cord to get hung up on the pickets.
