Wolfpack,
Just to give you a perspective of what is out there, I recently left for similar reasons to yours. I found a job not as a G450/550 pilot, but wish it was a G450/550. What I got was a job as a Global Express Captain, one of 4, with a company that was going to pay for my move, but told me that based on the fact that I live within 2 hours from them that I also had the choice to stay and drive. I decided to stay and drive and be paid for miles driven. Also, I get a guaranteed 10 days off per month on top of any other days off, all trips are Part 91 no charter, scheduled weeks in advance, and all of the trips are up and down the east coast,europe, and the Mediterranean, and any trip over 2 weeks long I have the option of comming home and swapping with another crew. Starting pay is $150,000 with all benefits paid for by the company, and I have no Glex time at all. The Glex is a nice aircraft also, and this one is loaded with all of the bells and whisles.
I can tell you this, I do not regret leaving at all, I am enjoying my new job much more so than NJI, but will say that NJI/NJA is a great operation as well.
