Are VPS hard to manage...? We just on shared hosting now and that's only costing few bucks a month...
I had a person recommend that if I wanted to ever go down the route of using a VPS for my sites, it's best to install Linux on a virtual machine to get used to using it. I think there's managed VPS you can get from certain hosts, but it'll probably cost more money than managing it yourself. I use shared hosting myself currently, I don't have the knowledge to manage the hosting side of things.
