IBM 5120. Who would be interested?

Hi all, I have a working IBM 5120 (BASIC version / type-model 5110-3) along with its 5103 printer. I want to part with it and am wondering where would be the best place to put it up for sale, auction, ... or just find someone who would take care of it. What is it still worth? I once saw someone trying to sell one on Ebay for $3000 but that was way too high... but I read somewhere else that someone was willing to pay $800 for it... As it is a heavy machine ("desktop" but about 50kg) it is not easily shipped and I am living in Belgium...So the main issue would be how to find someone local (even in the neighbouring European countries) who would be willing to pick it up. Or could it be shipped internationally? I thought it was a quite rare but is this correct? Any ideas? Thank you, Dani
