Hi, I'm interested in getting a wimax connection after reading some positive comments. On the BSNL site there is a plan for Rs. 750 with 512 kpbs speed & unlimited downloading. I have a few questions regarding this -1) What is the average speed one gets on this plan?2) Amount that one has to pay upfront including security deposit, advance rent etc3) There are 3 choices of device on site - indoor, outdoor & usb one - which one should I opt for?4) Lastly, is this Rs. 750 including taxes or excluding it. Thank You
