I have a Samsung Home theatre (DVD - plays even DIVX and 5.1) which I purchased for Rs. 10500/-. Extremely good to watch a good 5.1 recorded movie on it with awesome sound effects. Very very good value for money.
Another good system is Sony at Rs. 15,000/- The difference is in the wattage and of course the Brand Name.
Both good budget home theatre systems. Would strongly avoid the cheap chinese varieties
