Tazza, Thanks that helps a bunch. Hope you don't mind a few more questions. Looking at S150 or S160. Are they both always turbo? Are they essentially the same except 46 vs 56 HP? do they all require you to put in a code to start or are some key start? Do they all have Hi Flow aux, or is it optional. Thanks again, trying to learn as much as I can before making a deal. I looked at an S160 with hi flow aux, and power bob-tach, had a code to start, (rather have a Key), 2XXX hours $13000, nice exept concrete splattered around it. Thanks again. Bill B
