This is a difficult decision and is kind of linked to another thread.
A lot of the "low cost" carriers do self funded type ratings, it has become a part of the industry. Not a good part I hasten to add.
IMHO this should really be your last option, as it does decay the airline industry, and when times are good, and the likes of Ryanair or Easyjet need pilots and nobody is willing to pay for their TR, the airlines will type rate you.
However, at the moment it is a fact of life that people are prepared to pay the airlines for a cockpit seat. If you really have to do it cause there is no other way (which there always is) make sure you have a guarantee of a long term position. As very few CP's or DO's will employ you with low TT, a type rating and some line training. If you do not have a job offer, DON'T do it.
C130Dreamer, my advice to you, at your age would be to look at Corporate aviation. Age is often a plus in corporate, and if you are going to spend thousands of dollars/ pounds on a type, a biz jet type would probably be of more benefit. However, do your research, and do the rating as a P1.
