Is there any photo selling site like istock ?

One client of mine, wants to buy some photos from istock.
I made the mistake, to tell him that are included in my offer, without cheking the prices of istock.
After, I found that the photos of istock are very expensive! Compared also to other similar sites/services.
Does anybody know, any good site with the SAME QUALITY pics of istock, but in better price ????

SmugMug
Alamy
Flickr collection
Fotolia
