It's actually a good time to keep your 146 rating current. A couple of years ago there were some really good contracts around on the 146, in Europe, and I'm sure that once we manage to convince ourselves that the big bad recession is over, there will be a few eager start-ups hoping to take advantage of some extraordinarily low lease rates on 146's and RJs. However there will be very, very few pilots still around to fly them... so the 146 rating will be gold. It certainly was in 2007.
A320 and 737 pilots are very common now, and large amounts of them are out of work...
