Boys, don't be pennywise and pound foolish!!! Dime a dozen guys coming out with low cost model... Tried my hand at RKSV, had also visited their only office with 4 or 5 guys sitting and trying to do their business.. Good times it is alright, but we must be ready for when market falls and don't know if our money itself will be safe with these kind of guys.. I am sticking to Sharekhan.. I am not generalizing and painting everyone with one brush.. But atleast with RKSV, seeing those 4 guys sitting and trying to support I don't know how many people, didnt feel very safe..

Let's wait for their answer.
Meanwhile, consider this. Zerodha today has 15000 clients and offices in multiple locations. But 2 years ago they were new and hardly had 1000 customers when they started in TJ. I think that the broking industry too is changing. What all these discount brokers have in common is their risk management. They do not give any extraordinary margins - only what the exchange allows.
