Hey!
So I am currently doing the PGDL rn, and I started it straight after I finished my undergrad.
It obviously depends on each individual's financial situation, but I will say, doing the PGDL has made my applications this cycle 10000% better. I only got one (first stage) interview last cycle (I maybe applied for 7 firms). Whereas this year I applied for maybe 15 firms, and for most of them I progressed past the first round. I have now had 3 last round interviews / AC's, and secured 1 VS (still waiting to here back from the others!). I genuinely believe I wouldn't have been able to do it if I hadn't improved my knowledge of the law, been surrounded by my classmates who obviously were all applying aswell, and also the careers support from my University. Similarly, I got access to so much work experience through the PGDL, through clinics or other volunteering opportunities. I'm not sure I would have been able to do / apply for these without the PGDL. This really depends on the provider though so worth shopping around and seeing what is available. So in that sense the PGDL was worth funding for me.
Obviously if you managed to get a paralegal job then you would get a lot of similar exposure, but from what I have heard the paralegal job market is a mess right now.
I'm not sure if you are about to graduate or not, but another thing which maybe you find reassuring is that most of the people I did the ACs with were paralegals / career changers (the firms are large national firms), which made me realise that not everyone is securing a TC in their second year of University. So don't feel so rushed to secure a TC - I know I was panicked about this.
Lastly, you can work during the PGDL. Don't get me wrong, it is a lot of work, but it is absolutely possible to do 2/3 days a week. If you are planning on working during the PGDL I would recommend getting ahead on reading before you start just to help ease the load at the beginning because it can be a big learning curve.
Sorry that was a lot of info (I am currently procrastinating revising lol) but if you want any more info about the PGDL, PM me and I'd be happy to answer any questions
