opinions on a K13

I am a member of the council for my University gliding club - fairly new
compared to most of the people in this forum, but hey i enjoy it.

We currently own a K13 aircraft with a (fairly) serviceable trailer.

we have been offered an Acro with no trailer, and in order to buy it we
will need to sell our K13.

I was wondering whether it would be worth it - because the deal we have
been offered for the acro is not massivly great. and there are several
drawbacks.

mainly -

asking for a grant from the university.
selling the k13
not having a trailer with it.

Just wondering what some of the more experienced people think.

Thanks,
