Well so I finally went to Devi International on Sunday to check the installment offer.
Here is what it looks like for anyone else who is interested:
Model : PV80
Finance- Bajaj . The guy sits there so no hassles.
Mode of payment : 1/3 by CC , rest *8 monthly installments.
Downpayment amount :19650 , per month installment :4667
Total Cost of TV - 56,000. Cost of TV with installments :56986.00
So in total over 8 months I am paying Rs 986 more

Documents required : Copy of CC, id proof and address proof.
Hope this helps anyone else planning to go in for the installment scheme.
The TV was not in stock yesterday so was promised it would be delivered today or max tomorrow.
Just waiting for it. Got Jhingalala plus yesterday too

Thank you all u guys for ur help. Now I will bug u once I get the TV installed.
