Mahesh nice trip blog there mate. I think you should stop being a miser now and invest on buying a decent P&S camera atleast.
Now that you work in one of the worlds largest corporates and that you have a 6 figure sal' it shouldn't be too heavy on your pockets.
Frankly you are the only guy I have known who gets accessories for his car after the 25th of every month, while a few of us here are eager waiting for the next pay cheque
