purchase the stuff i said earlier, accept the offer, then go hunt down the frigate
however, focus on capturing the guy himself, and try not to kill him; if we get him alive we could force a higher bounty out of him for his freedom, or add him to our "crew" by recruiting him as a partner ship, or both, if we're lucky.
and if we choose the latter we could stage turning in the guy to get the bounty, then bust him out.
in the future will there be other ships available for purchasing?
