Best ever and I have used and i use a lot of different companies such as Uk2, Coreix, host gator, web fusion fast hosts, eukhost, webhosting.uk.com, rackspace and others i can't remember.
I've got a VPS with CWCS which has excellent support (live chat/ticket/email) and one with Rackspace. The CWCS server hasn't been down once in two years, which is incredible.
Unmanaged Dedicated from PoundHost for 2 years. No problems.
Knownhost for US vps for over 2 years. No problems. Future Hosting for US vps - all good bad been suspended without reminders for late payment once, unprofessional
Also just started using unmanaged cloud vps from RackSpace
Xilo - been with them for 6 years - still great - still never had a problem - A+
site5 - OK-ish been with for 2 years, a few probs, will be leaving next year
good responce thanks. I will leave it for a few days then will add them all to a poll so people can vote for there favourite hosting providers, this way we can see who is good and who to avoid.
