I was dead against them from the get go, but i kinda changed my tune. I bought the 070 to run on a mill, if id bought a NOS stihl 070 theres no way i could bring myself to run it on a mill, i dont have to feel bad about abusing the huztl 070.
I too have been looking at the build kits, specifically the 660 and the 372, mostly as training exercises.
My big gripe is the guys who try to pass them off as legit. If you want to build a clone then do it, but dont dare pass it off as oem.
Its like saying you have a Colt 1911, when really its a Norinco. Buy whichever you want but be man enough to call it what it is its either real, or its not.
