What is average salary of a 1st A/E at MSC?

[SIZE=1][SIZE=2]Hello, I am considering a career shift working for MSC. I see the posted base salaries for MSC and I realize each ship is unique, but how much can a 1st A/E expect to make average for total compensation?[/SIZE][/SIZE] Is there a Federal compensation wage limit? Is it still hard to get a relief? Does the West Coast Fleet pay more than the East Coast? Any advice? Thanks
