Photography Gallery & Ecommerce Plugin?

Hi,

I am looking to seek photos online and checked out a couple of sites like http://www.smugmug.com
and http://www.zenfolio.com but I want to host my won wordpress site and I'm wondering if anyone knows of a plugin that displays nice photo galleries that also provides commerce (could be an additional/separate plugin) to allow people to purchase their photos.

Do you know of any suitable plugins? Happy to pay for them.

Thanks

D.
