> I've been using HE.net's tunnels for a good long while now and they've been great for me.

Same here. As of about a year or two ago, my pings over the HE tunnel are only very slightly worse than those over my IPv4 interface, and I can't notice much difference in throughput. I've encountered minor issues with their tunnel servers from time to time, but usually by the time I notice the problem is resolved.

I also have to second that their support is absolutely fantastic. Plus there's always their forums, in case someone else has run into something similar. Many of tunnelbroker.net's users are equally friendly and helpful.
