P.S I did use Google and visited websites. Even send few email to support.

Alpari US and MT Trading are NFA regulated brokers.

Thank you, but this information is not very important for me. I was more interesting in deposit and commission.

Information I got so far:

Broker --- Deposit --- Commission P.R.T.
Alapri UK --- $20,000.00 --- $6.00

Alapri US --- $10,000.00 --- $5.00

FXOpen ---$1,000.00 --- $7.00

ATC Brokers is IB for FXCM and minimum deposit for MT4 ECN account is $ 5K.

MB Trading is $400 depo, $5.90/$100,000 round turn
