First of all I'd like to thank everyone showing interest and PM'ing me. I'll answer you all, but...I'm kinda short on time atm :-| I'm afraid it won't be untill sunday before I can have a look at the A4000's.
Second, I got quite a few PM's from people outside The Netherlands...but even more from people living close by (and I always thought I was the only amiga user in the neighbourhood ;-) ) Since I rather have someone pick them up instead of me having to haul them to the postal office, they'll be first in line. You might change my mind by offering me a ludicrous amount of money though :-P
Anyway, stay tuned, I'll post again when I have some more info on the state they're in.
