I haven't seen any comments or reviews about them and they seem to have some nice features. I trade e-minis and want low commissions (who doesn't) and want to avoid getting stuck in positions for hours, as I did 2 weeks ago with TS6.
I'd stay away from anything with "select", "gold", "platinum", "premium", or "pro" in the company name. Nine times out of ten the descriptor is lipstick on a pig.
