You may want to check out Hub66. We have had them on the island for a couple years now and they have been great.

They have a tower on Gunstock and can pretty much beam and reflect the signal just about anywhere. I get a minimum of 100 Mbps of speed on the island (which they guaranteed) and almost twice that in the off season. I believe I pay $130.00 per month during the summer and that price gets cut to $40.00 per month for 5 months during the winter. They do not throttle down service in the off season they simply reduce your bill. I'm not sure if this is special island pricing but assume it is...
