I'm located at tamil nadu, chennai, I am looking for a unlimited broadband or wifi plan with minimum file download speed of 600kbps.

How about services like YOU BROADBAND and BOINGO boingo.com Are they really good? YOU BROADBAND offers 1mbps file download speed for Rs.1102 per month under hurricane you package youbroadband.in/tariffplans/chennai_broadbandplans.php#dualspeed_plans (Under dual speed, Last row) Is this package really good.

Please suggest me some good high speed broadband plans..
