Picman,
Up until recently, I used a VPS server and had several Joomla, Wordpress, Zen Cart and other CMS sites hosted at the same time with no issue. Without going into detail, I had over 15 Joomla sites running with moderate traffic. It is an option you may want to look at.
I can't say enough good about HostDime's support. I started out on a shared reseller plan in 2003 and had been on a VPS server since July 2007 until last month. With any issues I had, HostDime resolved the problem in a quick and timely manner. At one point I was traveling, received a call from one of my clients about a problem he was having. Since I was driving and obviously unable to get on my server myself, a quick call to HostDime's support desk had the problem resolved within 30 minutes. It would have taken me longer to find a wireless hot spot to try to resolve the issue myself.
