stock photography sites reviewed

I decided to review the stock photography sites for my needs. I used the following keywords: computer servers, security, business, businessmen

The baseline I used was stockxpert.com. Its because its the site I'm the most familiar with and I have a subscription and bought single images with. Stockxpert has an excellent selection of images, the prices are reasonable, subscription is nice. The only thing I don't like about them is every now and then you run into an image you want but you realize its not covered under your subscription.

istockphoto.com
image and selection similar to stockxpert. Higher priced but you don't necessarily get more.

bigstockphoto.com
a site very much like stockxpert in selection, they don't offer subscriptions, but cheaper images if you want to download it in maximum resolutions.

snapvillage.com
a site very much like stockxpert in selection, cheaper subscriptions than stockxpert.

photos.com
dirt cheap subscription up to a large (but not X-large) resolutions, but you mostly get what you pay for, but worth a look.

fotolia.com
a site very much like stockxpert in selection, same subscription price, but cheaper highest quality single image price like bigstockphoto.com

dreamstime.com
same selections as stockxpert, not limited to "subscription-only" photos

fotosearch.com, corbis.com, punchstock.com, blendimages.com
I think these sites are for magazines where you need one image with a lot of x-factor that's going to leap off the page. Their pics with people have that about them, but they don't have much of a selection in the technology area. For other uses, its completely over priced. We're talking hundreds of dollars per image. And just because you're paying 1000x more, doesn't mean your images are necessarily any better. They got a lot of crappy looking photos too.

If I were to do it again, I would go with dreamstime. Their interface is not as nice, pricing and navigation is a bit confusing, but you get the same selections as stockxpert without the limitations for paying less for the subscription.
