Looking at a few 05 800 and 900 rmk's. I thing 2 are anniversary addition. What are a few of the major pro's/cons. Looking at weight and reliability mainly. I have not been around Polaris much and am not even sure if these are edge or IQ chassis. If this is posted in wrong section I'm sorry. Any insight on either size would be much appreciated. If this is a bad year, what is a better more reliable size and year. Not wanting to spend more than $5000
