If at all you are investing in Bangalore why don't you go for North Bangalore. As we all know that North Bangalore is the safest place for investment purpose. :) :)
Smondo 4 is also a good project and the price they are quoting is also reasonable. The project is expected to get completed by 2015 and Vasavi Pearl is about to get completed if I am not wrong.
I feel Electronic City is a better option for investment and you can also except good returns in the coming future because of the PRR project. You can also get good returns as some may offices are there. The region is well developed and has many reputed IT companies, industries and residential spaces. It also has some of the reputed educational institutions and hospitals to give better facility to the residents.
Vasavi Pearl is one of the project by Vasavi Constructions. The project is known to be approved by A Khata and banks like Axis and Corporation. I think the project is good for investment purpose. :)
