Dsl really cant touch cable modems. The dsl has its own bottle neck because of the size of the pipe. Its not going to go much over 2.5. Cable modem uncapped can do around 9.0 downloads, and nearly the same upload. If you dont believe that find an optimum online customer, and ask them. Im with comcast, and pay for the proplan. I get 3500dls, and 384 up. I normally have download speeds, to give you the other figure, of 400- to 500 KB/s. It really all depends on providers available in your area. For instance if cox is the cable provider, go for the dsl. lol If optionline, comcast, and a few others are the cable provider go cable. Im not well versed on dsl companies, as I steer away from it. The only nice thing about dsl, is usually your upload speeds tend to be faster than most cable companies standard plans. If I didnt have the pro plan, Id be at 1500 dl, and 128 up. Not acceptable to me hehe. Oh and the only advantage of a t1 for me would be if I were running a server. T1 speeds are 1.5 up, and 1.5 down. Other than that not worth it for a residential customer. The price is way out of line for what you get. Good luck.
