Being a Stihl fan, I didn't know if I would like the CS-56 I bought off ebay, but after having it a couple of months now and cutting approx 10 cord with it, I can say that it is a great saw. I switch which saws I use day to day and I can honestly say I don't hesitate to pick up the EFCO built saw. I haven't had any issue's with it, just fresh gas, bar oil and go. It does seem to have excellent air filteration, it doesn't need cleaned that often. I have switched it from a .325 to a 3/8. Just a good solid little saw, it needs a muffler mod, it's a very quiet saw, probably choked down to the max, also they come very lean from the factory, like most other saws. I wouldn't hesitate to buy another.
