Where to buy purse frames

I know Etsy has a lot of purse frames, but I'm trying to find a domestic supplier of purse frames that are plain nickel and "normal" size for a clutch. The Etsy frames seem to be a lot of embellished ones that I don't need. Any tips?  There's someone on Flickr who uses really nice rectangular frames with a nice curve in the top...so pretty! Unfortunately nobody there ever gives up their sources 

Thanks!!!

I guess it's a secret.   

I had great service and fast (& FREE) shipping from Meow Craft on etsy.  http://www.etsy.com/shop.php?user_id=5608076
