Last night I purchased a very good condition ms460 for a good price. Now I have an ms261 16 inch, ms390 18 inch, ms440 20 inch and ms460 25 inch. I am thinking about selling one of them, although I may not sell any of them. I think the ms390 is the odd man out due to the weight comparison between it and the 440. My only consideration is I bought it very cheap and I don't mind just tossing/leaving it in the truck in case I run into some wood in my daily schedule. I wouldn't do this with any of the other saws. But are the 440 and 460 close enough where I can just keep which one I like best. I could turn a profit from what I paid on any of the 3 larger saws. Any thoughts or ideas. I don't need all the saws, but can you ever have enough anyway?
