Since you know how to handle a heli, given the training and sim hours, I would suggest go for a 50 size. Various options are available and each model has its advantages. You grow out of the Rappy 30 quickly. I've had mine for almost a year and now I have 2 Rappy 50's. The power is just so much better and the autorotation gearing on the 50 helps a bit when ur learning auto's. Since you live in the USA, I would suggest an Align 600N, don't get the pro with the shaft drive - if you boom strike with a shaft, damage expenses would be a bit more. DON'T get me wrong I love my rappy but parts in the USA for align should be cheap and normally comes in packets of 2 or more and are cheaper than TT, which is normally only 1 part.
