Reliable broker that supports MT5 live and accept US trader?

Im in Search for a reliable broker that supports MT5 live and accept US trader.
I had narrowed down my search to 4 brokers, because all other brokers dont accept us trader or dont support mt5.
google doc for my complete list:
https://docs.google.com/file/d/0B-NvfAvDDP3WWW93WHU2LTRJWGM/edit?usp=sharing&pli=1

the 4 that i narrowed down to are:

AGM markets:
They sound like scam. Nerver heard of them, google search shows nothing with “AGM markets scam” but this scares me: “Deposit to your Standard or VIP account during winter and AGM Markets will DOUBLE your deposit!”

N2 Capital Markets: never heard of, don’t want to be ginny pig

mig bank: they have partner “penson futures” that accept us clients, but just got bought out by knight capital.

instaforex: they are scams: Instaforex, are they honest and reliable? @ Forex Factory
and http://www.forexpeacearmy.com/forex-forum/scam-alerts-folder/3484-new-excuse-confiscate-profits.html

Anyone have experience with AGM, N2, or MIG? Please share.

Best,
Dean

Hi Dean,
I’m looking at exactly the same question. I first thought that Alpari was a candidate, but only UK office has MT5 and US is still on previous version. I also have Instaforex in my list, but reviews are either very good or very bad. It seems that many brokers are waiting it out to upgrade to MT5, if they ever will.
Any broker has bad reviews at some point. Someone on this forum put it this way: ‘You have to try it out for yourself and see how it goes. Try multiple ones and see which one works best.’
