many websites are blocked in China, so proxy or VPN become absolute necessary to get information from the internet. I am using SSH Proxy supply by cosbeta for only USD 6$ whole year, it is fast and stable, satisfying me normally. But VPN is also necessary in some occasions when SSH Proxy don’t works well, though not frequently. For example, some software don’t support proxy.
VPN pay by month or years is to expensive to me for occasional use. It would cost me more than USD 50$ for a year. So the traffic volume based VPN would be a good choice. Pay as we use, and does not expire until all traffic volume is used. So I chose IVACY. It is cheap, 0.5€ or 0.7$ for 1 gidabyte traffic volume, 10€ or 14$ for 20 gidabyte is enough for one-year usage.

IVACY also accept payment monthly, unlimited volume. 10€ or 14$ for 1 month.
ibVPN http://www.ibvpn.com is also a great vpn provider. the internet connection is stable and there is a free trial to test before you buy.
