Bitstamp: How good is it to buy/trade

[bitstampindie]

Hi,
I am new to trading but not new to bitcoin. I want to purchase some btc and trade them on www.Bitstamp.net. They have been around for few years and is one of the oldest in the field as I gather. But before I proceed to buy btcs(planning to get about 3btc) from them. I want to see some feedback from the community here. Please give me some heads up about bitstamp on their efficiency and integrity.

All feedback are appreciated

Thanks in advance.
