Discount brokers

[mhertz]

I'm currently a customer with Ameritrade (Canada), but since they're were acquired by TD Waterhouse and all accounts will be transferred over, I am going to switch to a new discount broker. The two that I've been looking at are:

Questrade
Interactive Brokers

Any thoughts on the two?

Thanks!

Also, please let me know any information on:

OptionsExpress

Thanks!
