In the film "A New Hope", Ben Kenobi promises to pay Han Solo "2,000 now" for passage to Alderaan.
In order to pay this, he tells Luke to sell his speeder.
I assume both Luke and Ben have some modest savings. And, perhaps, they borrowed some credits from someone.
But is it ever stated - or is it possible to work out - how many credits they got for the old X-34?
