Anyone use a VPN at home?

[ChimpMaster]

I was looking at this one, which starts at just $39.99, but I don't know much about VPNs. Can you recommend another or even just tell me if it's worthwhile in terms of defending my home PC and data?

What do you gain from in? You're routing all your internet traffic through somebody else, which is only useful for hiding what you're doing from your ISP, as far as I can see. Or perhaps if you want to appear to be using several different IP addresses (say perhaps you have multiple logins on a forum - not that anything like that would happen around here).
