Firstly you may have problems getting a Stihl dealer to sell you anything without a Chain Saw certificate. I have a Stihl 023 which I've had for years (14" bar) and have in the last year bought a couple of Stihl 038 Farmbosses on ebay (18" bar). I like to have a carry bag for the chain saws so everything stays together - a Stihl dealer refused to sell me a bag without a certificate!!! Incidentally I have legitimate grandfather rights to use one. Stihl saws are great - very reliable, spares easily available and relatively easy to fix if things go wrong. One of the 038s was a wreck, and I replaced the piston/ cylinder/oil pump , some anti vibration mounts and chain the catcher and now it's a fantastic machine.
