Determine what you need first: Bandwith, Speed, Shell access (?), Price range etc. Then compare the various hosters available. Unfortunately, you can't really test a company's claims (Speed etc.) until you've set up an account there. So, make sure they've got some sort of test drive available, and don't order anything until you've tried out their products and you're satisfied.
If you think you need to upgrade, just do it. But if your provider has a good service, reliable, very uptime, I think you should not upgrade to VPS. :).
I will suggest you to go for VPS Hosting if you are looking to save some money, you will get large amount of Space and bandwidth and would work better than shared hosting package. I can suggest you the company I use take a look at UK VPS Hosting.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
