Anyone use Interactivebrokers or MBtrading?

[alekhine8]

I use MB - my only issue is that I can not access it at work due to a firewall. I can, however, view quotes and stuff with the software, just not trade.

IB has web trading features so you can avoid this problem, if you are in a similar situation.

Other than this, I've read they're pretty similar. Although MB won't direct deposit back to your bank - will only write you checks.

(I should move to IB?)
