Practical question on valuation of old systems

Well that's one thing that people here can never seem to wrap their brains around. A particular piece of equipment (in your possession, mine, or someone else's) may have a wildly different value than either you or I think it does (or should), for reasons which we may not understand. We must have faith that the person spending (what we consider to be a) a huge amount of money on something is doing it for a reason, and we're not qualified to judge the merit of that reason. It all boils down to respect for another person's judgment and opinions, really. Your Apple ///...I've never played with one, and I'd like to. I've never been a pre-PowerPC-Mac Apple person. I'd pay maybe twenty bucks for a ///, just to learn more about it. A person who lusted after a /// when they were new, though...like I did for the TRS-80 Model I...That person, and that person alone, decides what that machine is worth TO THEM, and the reason why is something that that person decides the merits of.
