It's all quite simple Bob.

For, to pick a figure, four out of ten projects, you will need a new tool to
do some, as yet unknown, process and that tool will be of, as yet unknown,
(hand/power) type, and of unknown quality (how much you spend depends on how
often you think you are going to be using the tool).

When the situation arises you evaluate your needs, the options available,
and there will be a few, your budget, then do the best you can.

Anything after that requires a crystal ball, mine is out being cleaned and
recalibration.

The key words above are "as yet unknown".

A final note, That four out of ten ratio may vary but there will always be
at least one out of an as yet unknown number of projects that will require
something new. So, when it come time to buy that unknown tool, budget
wisely.
