Should I self-fund the LPC?

I have secured a place on the Legal Practice Course but since I haven’t managed to secure a training contract I’ll have to pay for the course myself.

From what I’ve been reading in the legal press it sounds as though the jobs market is still tough for trainees. I’m therefore wondering whether it’s worth getting into £20,000 of debt with no guarantee that I’ll get a training contract. What do other people think?
