I am looking at getting either an 07 or 08 m-8 or an 05 900 king cat. Just wondering what the opinions are on these sleds. can get the knig for 5500 the 07 m8 for 6500 or a 08 m8 for 8000 which is a better buy. the 08 is new. others have 500 miles on them. Also what are the differences from 07 to 08 on the m-8. Thanks
