I want to have this explained to me.   I've often seen claims of purchases "for tax reasons" but when I do the math it always seems to make more sense to make intelligent business decisions rather then "avoid taxes" by buying things which are uneeded.  How will that 9660 ever "save" enough taxes to cover the tremendous hit it's gonna take the minute it leaves the dealer's lot compared to our 9600's which are going to be worth within about $25,000 of what we paid for them when they go to the old-combine's home?
