Duckie I have the older, slower one.  That has always been my complaint, that it takes to long!  I don't use it much.  
I have the ryobi version of the small chain saw, it is great.  no oil, it just does its job.  I also have the longer lopers like urs, and the 14" 40v chain saw.  Like you I'm pretty well fixed for trimming!
