Hello,I am considering switching to Dataone. I have the following questions. I hope some of you would be kind enough to take the time to answer those for me.1. Is buying my own modem from the open market (as opposed to from BSNL) a better choice?2. Would there any specifications to which the modem I would be buying has to confirm? If so, please list them? I did not find them on the BSNL website. Even if you could provide the URL where they have been listed, that would be very helpful.3. If I choose to buy, which one is beter - PCI or USB or the type that connects to the NIC?4. I intend to use my connection on one desktop only. So, would I be needing an NIC (my computer doesn't have one currently) if I choose a PCI or a USB ADSL Modem?5. What are the approximate prices of the three types of ADSL Modems, and those of NICs? ( ebay.in rates are a bit confusing, and they did not have PCI ADSL Modems.)Thanks in advance.
