I've always wanted to buy stock online, but I don't know if it's worth it? What's a good company to use and are there a ton of fees?

I just bought 100 shares of Sirrus this morning. I went through Scottrade. Their commision is minimal, and there is no minimum to buy.

Their site is:
www.scottrade.com

I've been happy with Scottrade as well. $7 a trade and it's very simple.

I bought some Sirius stock a few months ago when all the inital crap with Stern was going down, hoping he'd find someway to get out and go to Sirius.

I used Sharebuilder (http://www.sharebuilder.com). Pretty cheap, easy to use.

I bought 500 shares this morning at $3.88/share. Ameritrade is $10.99 per trade.

I want to buy some

But how do i do it? is it profitable?

yeah, buy now and while you can in the next few months....i predict it'll go very high once Stern is actually on the network..

I've been looking into this aswell, any tips?

I use scottrade.com too. SIRI had a 15% jump today, look for similar results tommorow.

what do i need??

Credit card or anything?
