I pay $75/month for 150Mbps via Comcast... and most days a speed test will say around half of that, and there's infrequent outages (averaging roughly one every month).
The only other service where I live is AT&T: 18Mbps for $50/month. And whatever you may think of Comcast, my experience with AT&T's service and customer service has been far, far worse.
