Price is OBVIOUSLY the most important thing here. Why? Let's say you get into a trade, and things change, and you want to get out. Why should you pay $9.95 a trade or even more when you can pay $1 at Interactive Brokers?

You don't need to call in and get someone to hold your hand and teach you how to trade. The internet can do that easily for you.

IB will explain their platform easily. Even if it's in US dollars, European stocks on the NYSE trading as ETF's will already have the exchange rate factored into the prices anyways.

You can also pay a small subscription fee for eSignal, and that will hook into Interactive Brokers, and then you get awesome real time charting.

Oh ya, when some brokers say that they get better "fills" that's a load of hoopla. Just place a limit order. Something that's web based, and doesn't have an installable platform to trade with is an inexcusable joke, and goes to show why many brokers in Europe are 10 years behind. Don't pay more than $1 per trade or you're getting ripped off.
