Hi!
A lot of this discussion has been centered around comparing "crap tools"
with "good tools", but the camera comparisons seem to have been, for the
most part, comparisons between "very good tools" and "very, very good
tools". Bill Rob described how his woodworking was improved by the
purchase of a $1000 table saw, but I doubt he'd claim another big jump
in quality if he bought a $2000 or $3000 table saw.
There's a point at which upgrading the tools becomes less important than
upgrading the operator. That point, of course, is different for every
operator and the trick lies in being honest with yourself when assessing
it in your own development.
I must admit, my little brother recently taught me a lesson. He
introduced me to notion of ROI - return of investment... Mark, you're
absolutely right. Starting from certain point, further investment brings
negligible improvement in return...
