what stigma?
honestly, coming from comair, i can tell you that you would not get an interview with 200 multi in the current climate. you have to have 121 or 135 time in turbine acft (fixed-wing).
i spoke to a comair interview just the other day. he told me what they are looking for, and he mentioned that they are hiring gulfstream guys quite a bit. doesn't sound like a stigma to me. i point blank asked him if they are cool with guys going out and buying 250 hours in a metroliner and he was very enthusiastic about it. it's the difference between getting the job or not getting the job.
i wouldn't worry about any "stigma". helo guys with half your time that "bought" time in a metroliner or something similar are getting jobs at comair while the cfi's are sweating it out in the tomahawk or 152. seniority is everything in this industry.
there are other options besides gulfstream. i've read about them on this board. eagle jet i think is one of them. sorry, i don't know all the names. respectable operations that don't get as much negative flak as gulfstream.
when i was in your shoes i consulted several cfi's at the school i went to and they all said the same thing. given the credentials i had they all said they would "buy" time as opposed to being an instructor. i'm not knocking the cfi profession at all you just have to consider your own personal situation.
again, i invite you to check out
www.aptap.org. i believe you will find it to be educational as well as motivational. there are a lot of guys out there in the same situation as you.
