I found myself ordering many of the same parts over and over so I compiled everything into a google docs a while ago for personal use. I shared it with a few friends and it seems to have some value. I converted it into spreadsheet form to share with everyone. I will probably update it from time to time as new parts are discovered. I'm hesitant to add ebay links in there but the sellers I linked have a large quantity available and have been relisting the items.
