Hirobo XRB SR Lama vs Blade CX Vs Twister Medevac

[dwoodys]

I'm looking to purchase my first 'proper' helicopter.
I know that the Blade CX is highly rated by you guys, but wondered what you thought of the Hirobo XRB?
I believe that this was one of the first contra-rotating models on the market, but has it stood the test of time and is it still one of the better models out there?
How does it compare to the Blade and the other obvious choice, the Medevac?
