I use Tor quite often. It is a very valuable network which should be supported with new relays and exit nodes. When not using Tor, it is helpful to use a VPN based in a country such as Sweden. I would have to recommend prq.se because of their support for privacy guarded by strong cryptography and no traffic or connection logging. As well as their on-staff lawyers and being staunch defenders of free speech. If you have not heard of prq.se, various well known domains have been hosted there. Including Wikileaks and The Pirate Bay.
In fact, when dealing in any sort of transaction where you must communicate with another party, you should be using Tor or a VPN with strong cryptography to protect yourself and to help in keeping your communication private. If you are US based, your web traffic, SMS, calls, etc. are all being monitored. Your transactions via credit card, retail outlet club cards, and so on are all logged and can be viewed in real-time by federal agents. To not take steps to protect your privacy is scary to me. Yet you will hear time and time again, "I'm not doing anything bad! So I don't care."
