OK.
First of all, a type rating should be paid for by Your employer.
Second. What´s Your work worth? A salary maybe? Will You want a place to live in, keep it warm and possibly also have food on the table? Or do You value Yourself so low that You are even ready to pay for Your working a good day´s work?
Third. If You leave all professional ethos behind and are willing to pay for a type rating, at least pick one that will leave you somewhat employable thereafter. "Glass cockpit" and "widely operated worldwide" should be rather high on Your list of priorities. An old 3-crew fuel-to-noise converter like the 727, the worldwide operators of which You can count on the fingers of one hand and still have most to spare, has style points, true, but apart from that, I would not touch it with a 10 feet pole.
But after all, it´s your choice, as the consequences will be Yours as well to handle.
So: Choose wisely.
