I'm surprised anyone would still be working a Bell-47. Those things are worth their weight in gold nowadays.
Not really, you can pick an old one up in decent shape much cheaper then a new R22 or Schweizer 300.
I know an operator who still operates several 47s, doing wild mustang round-ups for the BLM. The 47s are great for that, only trouble is that it's getting more difficult and expensive to find parts.
Personally when it comes to small helicopters, (and having worked on both) I'd take a 47 over the much more popular Robbies any day.
