Another do the course.
Doing the course you'll figure out if it's "you" or not.

If you really like it (likely) then you'll probably sell a kidney to get one.
You could also go SCR (first), which is waaaay cheaper. ie 2nd or 3rd hand dolphin etc. The're cheap as chips, and although not as capable as ccr, it'll get you into breathers way sooner.
