What I am getting at here is the initial investment in tools and equipment.  I have two recent examples:

Auto repair tools and equipment-- I recently invested in a hydraulic floor jack, jack stands, wheel chucks, and other miscellaneous tools.  I made the investment in these items because they will help me save on brake jobs, oil changes, and tire rotations.  However, there was an upfront cost.  My recent brake job savings more than covered these upfront costs several times over-- every job going forward using this equipment or tools means pure savings.

Chimney sweeping tools-- I will be sweeping my chimney this weekend.  I laid out $50 for the brush and rods (I already own a ladder).  Around here, a contractor will charge $100-175 each visit-- I will recoup my upfront costs the first time out and get pure savings every time there after.

Bottomline, if you will use it again and again, the upfront costs shouldn't discourage you-- just be sure you will see recurring savings by owning the equipment and tools.
