If you want to throw more money to AC for good servers that's very welcome. It wasn't deducible from your OP that you will host more than just the clan site on the $5 webspace and that you plan to buy servers as well.
If you bought only VPS and wanted to get rid of your servers one day, you could just move the sites to normal hosting unless you use special settings and features, which you can't use now. But I agree with the lagging, if you have a low end VPS and/or use it improperly or get attacked on the website, then yes, it will lag. Your webhosting offers the same specs as VPS, they just don't tell you or don't limit you until you use too much. But again, I welcome more good servers for AC and had you said you were to buy some too, I would never have posted my reply in the first place. The server price range you are looking at seems reasonable. Make it an EU server, I hear Germany is cheap in comparison ;)
