What's the lowest price for a ship that one can talk Stan down to in The Secret of Monkey Island?

SPOILER:

You can only talk him down to 5000. He won't go lower. Sorry, but the game's gonna make sure you're broke before you get to Monkey Island itself. :)

Actually, I just made Stan accept 4000. You first offer him 3000 3-4 times and then 4000, once or twice, and he'll accept it. Hope that helps :)

We were playing through the Special Edition - and we somehow were able to get it for 3000! Clip here, but you can watch the full broadcast here
