Really! The selection is amazing and the website is excellent (except 
that it's hard to save direct links to specific products). The only 
thing to really complain about is the pricing, which can be high. If 
you've got no other source for something, though, McMaster has 
usually got you covered.

The website's drill-down product selector is great. When we wanted 
some rubber sheeting for a kitchen countertop, I easily found an 
FDA-approved, self-adhesive product that worked great. (It's called 
Buna-N rubber, for those keeping track. ;-)  If nothing else, you can 
use the site to learn about what's available, such as different types 
and qualities of rubber, plastic, metal, and so on.

I'd like to know, myself.
