[Parts for Ryobi 3" brushless saw]

 Have almost new PSBCS02 3" cutoff saw, I need the 3/8" spacers/washers that go on the arbor.  Ryobi site only list warning labels as available parts? These have flats on 2 sides so they want slip, can't find any like them anywhere.

[Ryobi angle grinder brushed vs brushless]

 my Ryobi old brushed type angle grinder does a good job but has a reputation of being tough on batteries, just wondering if anyone has upgraded to the newer brushless type?  

[Where to get replacement parts]

 I need the blade adapter for Ryobi 5 1/2" lithium + 1 - 18v skill saw,  where can you buy small parts like this for Ryobi 18v power tools?

[Anyone compare 40v brushed to brushless chainsaw]

I have a older 40v 12" Ryobi brushed chainsaw, been a good saw but chain speed is slower than a small gas saw.  I have been looking at the 40v 14" Ryobi brushless and wanted to know

if anyone has ever compared the two?  I know brushless claims faster speed and torque, but all brushless tools do that so I need a real life review/comparison.
