As an Ideale fan, I'd say I've never seen more than 15-20 Ideales on ebay at any one time. This is amazing--- but a quick glance through the list tells me some have way too high of an opening bid, IMO.
Also, several of "NOS" ones don't appear to be new. Too much paint chipping on the support rails in the first place. I won a true NOS Ideale 45 back in January and the rivets were waxed over to prevent corrosion. None of the current ebay NOS examples seem to have this feature. In this picture I've cleaned off three of the rivets. But you can see the ones still covered.
