I think this has been discussed in a separate thread on sony 360 that the Sony's cannot be modded. However, a Region A player may not have too many issues as there are lots of options available and the movie prices are price competitive.
However, the risks are that from the last 6 months I have noticed that Amazon UK is consistently cheaper than Amazon US by around 5USD per BD or even higher. Secondly, many BD's in India may not play as they will be Region C.
Currently, around 60-75% BD's are region free. I would think you are better off buying a Panasonic or an Oppo Bdp 80 at the same price which can be made region free much more easily.
