I won't dispute any of your figures, but in the older BERG catalogs they 
listed prices for everything and I picked a component line based on price.
(and everything in the book was strong enough for my needs)

If you dont need the heavy duty stuff, these are the prices I found for
what I wanted in the Min-E-Pitch line. ( cable chain system, chain pitch
is .157" and 7/32 " wide    100LB tensile str.)

Polyurethane cable chains (steel cable molded inside) have the advantage of
never needing messy lubrication

If you use the plastic gears (delryn) these are the prices

I am getting myself a McMaster-Carr catalog soon to check out their lighter
duty stuff myself!

My BERG catalog is brand new. When I called for the quote, I asked them
for a price list and was told that they are not made available. Not offering
price lists to go along with catalogs is a MAJOR pet peeve of mine.

I'm also kind of impressed with McMaster's no minimum order.

My current project requires moving a 48 Lb. load so I figured using steel
drive components was a prudent decision. Next time I need lighter duty
drive elements, I plan on doing a simular price comparison. I'd also
be interested in hearing anyone elses results.
