Instead of a VPN, you could consider an open proxy.  Unfortunately, you get what you pay for.  You can find free, open proxies, but they tend to be unreliable and can disappear entirely.  This makes it hard to maintain an up-to-date list.  Also, note that non-commercial open proxies may be run by people who don't have your best interests in mind.  They may inspect or interfere with your traffic and personal information.
