DSM Style,
I own a dedicated server from:
http://www.hostforweb.com/
For my Webdesign stuff / hosting. I have TONS of unused space / bandwidth and guarentee 99.99% uptime.
Anyway, I'd be more then glad to donate it if you'd like. Let me know. By the way migrating from this server to the other is easy. All you have to do is backup the MYSql Database, keeping the structure. Then on the new server, import the database, reinstall all of the php files that come w/ vbulletin and voila.
The debate about cable and dsl. Most of the time, Cable will provide overal more bandwidth, however, DSL provides faster response (ping) times. So when your just surfing the web and not downloading, DSL is often faster; downloading large files cable is. I've had both, 2mbps Cable is what I currently have and my 1mbps DSL seemed faster and was much more reliable....
DSMStyle or DSMChick, let me know if you'd like hosting.
