If you'd like to run a VPS, I'd suggest you to look for a managed one with cPanel. cPanel is a piece of software that facilitates a lot configuring the server, while managed means that the support guys will help you with initial configuration of the server, and also help you out with config/upgrades whenever you need help. It's a bit more expensive than non-managed, but if you don't know how to manage/administer a server, than it's essential. You can find a decent managed VPS in USA from 20 $ and up.
Similarly, in the case of VPS, there are several users that are using the same server but they are isolated from each other. It means that no one will be affected by how much resources another is using. You will get the speed and security that you need without compromise. It is almost a perfect scenario because you will get the benefits of a private server with shared cost of services.
