I just moved to philadelphia and I've been looking for the cheapest way to get broadband internet. I stumbled across these guys - http://www.closednetworks.com - they offer high speed internet for only $20. It sounds like a great deal, but I've had lots of great deals turn out to be "too great". Can anyone tell me whether these guys are for real, or tell me any drawbacks about the technology they use? Thanks a bundle.
