Where is the best place to purchase cake pans at a reasonable price.  I am looking to add to my pans and don't want to spend a fortune doing so.  basically looking for some rounds and squares.

AIf you are purchasing several at one time, I recommend ultimate baker dot com. They have competitive prices &offer 10% off $100 & 20% off $200.

I really like to buy from http://www.lloydpans.com/standard-pans/bakeware/cake-pans  Free shipping on order of $200+. 

I have the bare aluminum [Silver-Kote™ wasn't available until recently and Dura-Kote™ is too dark] and they're great quality and a nice weight. 

I buy 3" pans whenever I can and bake 2" layers in them.  I get nice full 2" cakes that are pretty flat to start.

If I purchase again, I think I'll try the Silver-Kote™ option.
