So far, weebly.com is my favorite template website host. Not only are their themes attractive, very customizable and easy to update, but they offer free, slightly limited blog pages (pre-linked to Facebook and Twitter), online store modules (that work with either Paypal Business/Premier or Google Checkout), Search Engine Optimization, nice-looking slideshows with several options, plus a whole bevy of other free features, including using your own domain name.
More features are included with their very reasonable hosting ($3.99/month for a year, prepaid). Okay, let’s just say Weebly’s an absolutely brilliant company with a goofy name and quick email support, going strong since 2007 and I am not paid by Weebly in any way to say so.
This site is built using a modified Weebly template.
Website Tonight® Templates
I also customize godaddy.com Website Tonight sites. Their themes are are more business-oriented and have less options for customization, although they are improving. There are some really good Website Tonight features: you can change background colors of their site building units (text/photo areas, etc.) which they call "blocks," you can "share" linked blocks throughout the site (which change automatically when one is updated), and have the (extra, paid) option to host your site on a secure server — all of which you can't yet do without intense coding on Weebly. I've just been checking in and see there are several improvements that have been made lately — one of which is to their slideshow feature, which was badly needed. I'll report back when I know more and can take the time.
Also on the plus side, GoDaddy offers exceptionally helpful 24/7 phone support, plus the dependability of a company with a long track record.
These are just my opinions from my experiences. I'll add other template site reviews as I learn more.
