Thanks CR888, I see Bunnings has the little Makita for $250 standard price every day. I suspect it's because Makita is running out the older non emissions compliant stuff & I guess it will become obsolete not to be replaced (If our emissions rules mirror the US). I also hear a rumour that the DCS 7901 are currently selling for $999 same thing it will go to the 7910 version.
But that said I've now really warmed to the idea of the MSA 161, I also see they have new better battery released in the UK 4.0 hr/amp > 4.8 hr/amp same weight. My budget, or more to the point justifying what I'm willing to spend. It's slowly going up as the CAD grows stronger so I'd rather just buy what I want. I'm wondering if you have any experience with battery top handle saws or have one to compare to your little Makita.
