I've been using addr.com to host desotonet.com. They're $10 per month. Their service has been good but their price seems high compared to others I've found. My all time cost leader is ucvhost.com. They're REAL cheap ($1/month for 25 MB) and hosted in New York but their support is in New Delhi and somewhat hard to interact with. The good news is that once you get them up and working, they work real well.
Most recently, I've come across globat.com. They're in California. Their current rate is $7.95 per month for 2.5 GB. They regularly run specials and I got it for $3.98 per month for the first year. I'm looking to move my photos from photoaccess.com to my own site.
