craftgrrl | US suppliers for jewelry findings and components?

i am mainly looking for bulk ring blanks with trays in brass ox, copper ox & antique silver but also findings like headpins, eyepins & jumprings. i found pandahall.com which has everything i need at good prices but for the amount of stuff i'd have to order as minimums, shipping is ridiculous.

here are some examples:

http://www.pandahall.com/wholesale/ring-components/232882.html
http://www.pandahall.com/wholesale/ring-components/434452.html

1) does anybody know where i could find such things in the US in those finishes a la one stop shop? i could get bits and pieces on etsy from various sellers but no one has all the finishes in a variety of shapes and sizes like pandahall.

or

2) is anyone else interested in joining in for a bulk buy from pandahall? most quantities are 100 minimum and even as manic as i get, i couldn't use 1000 ring blanks.

thanks!
