Used them for the last 7 years, for a number of different sites. I've never had any technical problems that weren't solved with a quick phone call. And they have knowledgeable people answering the phones. I've moved sites from simple low, volume shared server all the way up to dedicated server, added ram and disk space, and transitions have always been smooth.

Currently running a drupal installation with 20 web sites on it. They host something like 100K web sites. Systems are FreeBSD and, depending on the level of service, you get ssh, ssl, sftp, separate ftp logins to specific difectories, good indexed pop/imap/webmail system. Easy to manage custom DNS. You can set up multiple web sites on a single shared IP with having to pay anything significant. You can manage any number of sites, with separate or shared IPs on one account.

The big deal for me has been stellar reliability and great tech support when needed.

I don't want you to go on for pages, but am I curious:
who are you to say 207 years of Supreme Court decisions are wrong?
