I had similar requirements.
Go for Sony Cybershot H50.. it will just come inside the budget. I Got a deal at DASS store in pune for 18.9k. Ditched it and imported a Panasonic FZ28. Check google for specs n ratings.
FZ28 is top rated followed by SX10IS and H50
FZ28 is definitely not available in india. SX10 isnt either. H50 is the best bet if u buy from india.
You can buy the FZ28 off ebay for around the same price. Mine was US$392 from a HK based worldwide seller inclusive of shipping(free) 8 gb crard and 2 extra batteries + other stuff
