Anybody know much about this machine? I'm trying to decide between a Cat 228, Cat 246 (2003), and a John Deere 317. The Cat 228 is high flow which is a bonus for snow blowing, but I can't find much information on the 228 - it's a 2000 model. Anybody know if they were good machines? Problems? Any opinions on high flow and resale? Thanks, -john
