You can have a look at FlightSafety Intl. That's where I did my ERJ training some years ago. Training facilities are good.
But like it's been said above...if you've got other options, don't purchase yourself a rating. Especially this one, since it's quite hard to find a job with an erj rating and low hours. I don't know where you're from, but in Europe there are only a few erj operators.
