I use Wordpress, also, hosted at A Small Orange (http://refer.asmallorange.com/13697 — Disclaimer: that's a referral link). I've found them to be the most affordable and easy to work with host that I've ever had. I pay $50 / year for hosting and $10 / year for my domain name ( http://www.bryanray.name ). That comes with 750 MB of space and 15GB / month of transfer bandwidth. They have a smaller plan that's only $25 / year for hosting with 150 MB storage and 4.5 GB bandwidth. All of their plans have unlimited databases, email addresses, subdomains, and add-on domains ( http://www.christian-gamers-guild.org is also hosted on my site, and the only extra I have to pay is for the domain name). It will probably take a little bit of learning to set up there, but they've got active user-to-user support forums where someone will likely be willing to walk you through getting things configured.
Another service that's been popular with people at my university is the Cargo Collective: http://cargocollective.com/ I'm not real sure what the features are, but one of my friends has been very happy. From what I understand, it's an easy to use template site with a content management system similar to a blog. His site is here: http://www.ludlowdesigns.tv/ Their page is not very forthcoming about how it all works, though, so I can't say much more than that.
