T3, mmmm yummy. Fiber Optics is big bucks. I used to be a Structural Cabling Engineer, and installed many a feet of Fiber lol.
I currently have Comcast Cable, and its pretty good. I have seen DSL speeds faster, but its currently unavailable in my area. We were the last to have digital lines installed. Hell, Epping, NH had broadband years before we did lol. I remember we were the last to get Caller IDD too! Damnit! lol
With a little registry tweaking, you can speed up your broadband connection
