Rackmount shopping

[Neil Joseph Schelly]

This isn't really related to Linux persay, but I'm sure someone here can help.  
I'm looking to buy a bunch of rackmount accessories for our new datacenter 
installation at work, including shelves, power strips, cable guides, etc.  
Has anyone got a good source for this stuff they can share?  I'm all for 
local vendors if I find one, but it just doesn't seem easy to find this stuff 
even in the online world.
