I have no problems with CS New Media's Plesk setup, I am a happy CS New Media customer and use plesk for managing my reseller hosting package, and its simple and quick, I prefer it over cpanel (which is what interface I have for our VLE package at work) so much more user friendly and nice to use I find Plesk.
But saying that going to have a closer look (maybe going to have to be next month I suspect as will have to have both running at same time to do the transfer etc which means double the cost etc.) at Carls VPS as my bandwidth usage should be come under the limits..
Also now that I have found this it should be easy to move from cpanel to plesk http://www.webhostingtalk.com/archiv.../t-383144.html :)
As said Rackforce is great but the servers being hosted in the UK would be useful..
