www.franticstamper.com has some lovely stamps. They require a bit of browsing because it's just pictures of the plates, but I have bought quite a few. I first came across them when I got a free copy of Vamp Stamp News when an order from a totally different company went missing, and when they sent out a replacement they included the magazine.
Here's the link to the page in Fran's site -
