about this mystical grainger catalog

Hey all...

People have been talking about this wonderful catalog...well...how do you 
get ahold of one.  I am particulary interested in getting a different 
lighting system than i have now (which is a rusting shop fixture).  

Additionally...can anyone explain the difference between T8 and T12 bulbs???
