The 1mb dsl is way better than 3.1mb evo, I used to get 512kbps in DHA Phase IV, Karachi (in the house), and around 700kbps in Islamabad (outside my house). The max I ever experienced on an evo device was around 1mb in Blue Area, Islamabad.
For your seeding purposes, you can get a cheap seedbox for as low as $10 like
here. The hard disk space will be low, but enough to improve your ratio.
You are currently paying around Rs. 850 - 900 I guess, and you are ready to pay around Rs. 1000 more, which makes roughly $10.
However, this option is good only if you wish to maintain ratios on private trackers.
