Is it possible that after many years of sipping coffee at FL330, you might actually miss flying that 1960's built aircraft?
Err in a word.....no.
I think the issue of paying for endorsements is much harder to swallow in Australia (hence the passion shown on the thread) given that you already have spent so much time and effort to get a start. If you walked out of flying school and bought an endorsement (ie Europe) I think it would be slightly more palatable. However in Australia you have already been through the ringer and most guys would not have endorsement money just lying around, so it is only adding insult to injury.
However as said before there is not much you can do about it so either stay where you are in GA or regionals, or somehow find spare 30G.
