I've been using VPNSecure for a little over a year. Works great, simple interface, policy that no records are kept, etc. Got it from GDGT Deals for $25 for a lifetime subscription. I figure even if I get a few years out of it, it was well worth it. So far, it's been great. They have a lot of other VPNs on sale there as well.
