Anyone use Interactivebrokers or MBtrading?

[Packerfan1]

Hi all:

Looking to start doing some swing trading soon and was wondering if anyone here uses either Interactivebrokers.com or MBtrading.com for similar activity.

I recently opened a Scottrade account but since I"m only starting with about $10K (20K w margin) I'm concerned about the ability to make any early headway at $7/trade when I'm looking for 2-3% profit taking on each transaction.

Obviously paying $1 per side vs $7 per side would be great but it doesnt help if IB or MB is unreliable/bad quotes & fills/ etc.

Anyone have any experience/advice? Thanks. I might post my experiences once I get started for those here who are interested.
