A bit late, but may still be helpful info. One of my favorite professional
websites is _http://www.thomasnet.com/_ (http://www.thomasnet.com/)
Started as a clearing house of equipment/industry/manufacturers of
stuff that many people used to find ergonomic tools/options, but has
drastically morphed. Great for finding tools you have a "concept" for
but don't know where to find (for me the first things I looked for were
pneumatic chisel and pallet handling devices). It is a monster
site now, but you can link to hundreds/thousands of catalogs
from one site which helps when you are window shopping and
costing things.
Catching up,
Dee
