Tradeking v Scottrade v Interactive Brokers

HI I would like some input on choosing a broker. I can't decide between tradeking, scottrade and IB. Here is why I like each of them:

Tradeking - 4.95 flat fee trades, nice learning centre (at the min I want to buy equities both UK and US but I want to learn options and they are meant to have a good application for this)

CON - there stock research facility is bad I hear and poor charting too

Scottrade - $7 trades, great research and back testing and market information

CON - no learning

IB - one interface to manage all finances, apparently cheap but I dont know the commision. Any one know? Lots of market info

CON - aparently bad customer service, dont know commission

I am hoping some feedback will help me decide. I also tride thinkorswim but the paper money platform is confusing to use. Its slightly more expensive aswell.

Any other suggestions will be welcomed!

Thanks guys

Also if I live in the UK (and national) does this eliminate the above?

What are you trading ? ie, UK or US stocks ?

Are you trading futures and options?
