2LNBs are enough.my advice is DONT go for Dish for FTA.today or day sooner most channels(I mean best channels) are gonna be paid.get SUN DTH -which bundles all kannada/telegu/tamil channels + hindi channels for Rs2000. one year subscription is free.from next year onwards they will charge Rs75/month.

I took Sun DTH on Jan 14th this year.I never repended for taking SUN dth connxn.picture quality is the best among all DTH providers due to MPEG4 video streaming.
also ,IN sun you can buy pay channels too.
