The Price Of A Fast Connection And Question Of Mtn And Glo 3.5g Services

Can someone out there please enlighten me on approximately how much one can acquire a Ku- or C- band high speed internet connection, and where one can possibly get the best deals (in Lagos)? What are the subscription rates?

I must say that, although the MTN and GLO GPRS services are somewhat normal for surfing, downloads can be hell(Opera+Firefox assisted).

Is it possible to improve on the downloading experience(using MTN/GLO GPRS)? If yes, then how?

What is the optimal (system/processor/RAM) requirement for the optimization of the browsing experience using MTN and GLO GPRS?

Answers wanted urgently,
