The closest thing I can find is Forex Peace Army, but even that site seems a bit iffy. All other broker review sites are just affiliate sites in disguise with heavily biased/faked reviews. Ugh.

That’s exactly the kind of site I do not want. Did you notice the referral links? It means they get paid when you sign up for a broker if you use a link from their site. Those reviews cannot be trusted.
