I like mine... I'm planning to put together a photoshelter account, but until then I'll be on flickr, and probably still after that. It's pretty cheap and has a decent amount of stuff to offer, I think.
Once I get my photoshelter account going I'll use PS for stuff I own the rights to (so I can sell it) and flickr for stuff I don't own the rights to (so I can just display it) until my pro account runs out atleast.
