I don't believe you can disagree though, the argument is that you move money from the governments hands to someone elses hands.  As far as pay down debt with the savings, what a crock.  If I have to pay down debt to see 8% return, I probably had to carry the equipment purchase on a loan, so it is still a wash.

If you are looking at savings, take a deferred payment in good years till after the first of the year.  When a bad year hits, everything will catch up and you still have the tax savings without the purchase of and loan associated with unnecesary equipment.
