A $700 repair bill can make a $500 specialty tool look like a bargain. Spend the money on the tool, do the repair at home, and suddenly the savings seem obvious. Except the math does not end with $700 minus $500.
The tool may require additional equipment, replacement parts, supplies, or another tool you did not know the job needed. A mistake can turn a manageable repair into a much larger one. And if that $500 tool spends the next five years collecting dust, the savings never quite look as impressive.
