I went with a local wireless broadband provider. I had to buy a directional antenna for my roof, but now I have 3MBps symmetric w/ latency comparable to a land line, $50/month, (6mbps/$80 iirc) and they're customer support is a pleasure to deal with, especially compared to comcast...

The whole think is based on motorola canopy, though newer technologies might be available elsewhere.
