First, I suggest you take a look at the Rotorheads thread and post there. Many Rotorway users / threads.
Second, take a trial flight to see how you like rotary. A G2 may be your best bet to trial / train but R22s are the most common and thee are quite a few S300s. R22 is the least stable platform therefore slightly harder to fly. If you can afford it, the R44 is a more capable platform to learn on.
Third, can you legally get a single engine helicopter into your place? I don't mean planning permission or angry neighbours but the "land clear" rule. Without the engine the auto rotation profile means that you decend at roughly 45° ish. Basically, what you can see past your toes when entering autorotation is where you will land. So you need to have green space available to you for your route into your landing site and back out again.
Without that clear route in / out you can't take your machine home.
Aside from that - go for it! Helicopter flying is absolutely fantastic!
