I've been with Photobiz for about 3 years now. Very pleased with the service. They have come up with many new templates and features... all for free. Great customer service...easy to use...
Click on my main photography site link in my signature...it's a Photobiz site.
You mean the templates and features are free....not the site, and hosting of photos.
I use Zenfolio, I am semi happy with it. The pricing is ok, they do take a bite out of your profit if you use their storefront products. As far as custom products its not bad. I wish they were a little quiker with new features, like blog integration, templates, and things.
You haven't really said what you want in a site. Most places are similar, but they have different little features that make them stand out. Write down a list of 5-10 things you'd like your website to do, then start matching the different sites to your list. The service that matches your list wins. You haven't really given us enough information to help you decide. If you just want a generic place to put photos, Flickr will be perfect. But they are not the best solution for a lot of photographers. Help us, help you.
