good low commission broker, $2k start

Hi guys,



I was about to sign up to interactive brokers, but realised they have a minimum of $10k, I am starting with

Only $2k while I save more.



Can anyone recomend another good broker for US trades with cheap brokerage that will allow a $2k starter amount?



I am with Halifax, but as well as being $13 per trade one way, they also don't allow me to trade some stocks like $APTS that I planned on bying today...



Thanks,



D.
