I think it depends a bit on how much time you have to shop for trainees and how much effort you put into learning the game straight away. If you're not high on both, training a Star or Allstar with great starting skills can be a good way to get a hang of it without spending too much time and effort, and be able to get a decent starter and backup for later. If you can get a PAS for a low price like that, that's great. Main thing is that he shouldn't spend too much money on a trainee that he's not going to train properly (unless he wants to dive into the game with a mentor quickly).
