hey. I have tested several VPN services and i came across one of a user BTguard and he was not satisfied because of the slow speed. I will suggest you go through this list of top 10 vpn services here
I have used few of them and they are very good !!

buy? why would you buy something that can be achieved using free and establish secure methods. OpenVPn comes to mind.
If you understand what a VPN really does., its more than just installing software (the client side). You need something to connect to (another client, or server).
I have used very costly solutions by Nortel (now defunct), Cisco, microsoft, etc. How found that free solutions worked just as well. The only drawback is from a support standpoint, if you need step-by-step setup and configuration help, often a paid solutions is a bit better if they offer support. Where-as the free and opensource projects you are on your own, have to deal with poorly written documentation or trial and error.
if you really need a VPN? (ask your self do you,do you know how they really work)? then go for a opensource solution.
best of luck with your security setup.
FYI btguard is BS its for bit torrent and no one should support torrent in here...
