Thank you for all the responses.
Part of the reason for the post was just to get myself moving forward on this project otherwise the computers would just sit there for another year or two.
I likely won't get a chance to open them and check out the inside or test them out until Monday but I'll update then. Monday I'll take everything and lay it out. Photograph it, test it, etc.
I was unaware of the battery issue so they were never removed. If they leaked they already leaked. I don't see waiting a few more days will make a difference now. Hopefully they didn't.
I say try to sell it to someone that will use it and not hoard it or sell it to turn a profit. There are lots of us out there who have been looking for a reasonably priced 3000/4000 for years.
This is pretty much my position. I want a fair price but I'm also interested in them going to a good home. These were a big part of my adolescence and I was a big Amiga advocate so I want them to go to someone like myself but who has the time to use and enjoy them.
Dealing with my GF's father's stuff after he passed we gave a lot of semi-valuable items to what we thought were good homes and some of the stuff went on to be used and loved by the people we gave it to and other stuff ended up on e-bay being sold for a profit -- that was quite annoying so I'd like to avoid it.
The US shipping is not a big deal as my business ships stuff out of the United States twice a week so there would be no customs issues. That said if I could avoid shipping altogether that would be a bonus as it removes a risk of damage from the equation. I should have started this earlier as June involved a decent amount of traveling and possibly could have worked out for personal delivery.
