I just got hooked up with Hilti's Fleet program they have for tools. I've been really sick of buying batteries and paying for repairs for my tools. You buy a cordless drill for $250 buck and in 18-24 months I find myself paying for a repair and replacing batteries. That's $100 for a repair and anywhere from $75-125 for batteries. That tool just cost me $450-500 in the first couple years! With Hilti they have a program where you pay nothing up front. I got my new SFH 18 hammer drill driver for just under $15 a month. It's covered fro 3 YEARS. They gave me $75 trade in for my old stuff too. I never have to pay for a battery again. No more repairs. Nothing. Hilti repairs their tools and have them back to you in three day, so the down time in minimal. They do this for all their tools, I just got cordless now on the program, but if you have tools that you replace alot, this plan is the only way to go.
