Hi narmadha how are you...

Carrara 8 Beta 1 (Win/Mac)

If time and money are important to you, then you'll want Carrara 8 Pro. Not only will it save you both, but with support for 64-bit

This is the best one by far as there are so many options to choose from and they have thought of everything.

U see ds site is one of the sites that has helped me so far. keep it up. kudos to you all who helped in making thsi site what it is.
