Stock Trading On Line

Is there a good/cheap on-line stock trading site for Canadians?

Or can Canadians trade on US web sites?

questrade.com (canada and us stocks)

by far the cheapest, doesnt have the analysis and what not that other brokers might have,

but for 5 bucks a trade, no minimum monthly transactions, no monthly fees,
