SunRocket offers $10/month plan

Full disclosure: SunRocket is my VoIP service. They've just announced a $10/month plan that allows 200 minutes of outbound calls in North America and unlimited inbound calls. There are discount per minute rates if you go over the 200 minute mark. That's a good deal for a LOT of people. Vonage currently offers 500 minutes for $15, however for just a little over $16 per month, SunRocket offers unlimited inbound and outbound calling (via a $199/year lump sum payment).
