Price guide for vintage computers

Frankly, I don't really care at this point. I don't do it to make money. I have never bought a piece because I thought it might be a good long term financial investment. ??? Of course I want better deals. Go figure, eh? I don't want classic computers to be a "market" at all. I would rather think of them as something that is traded, not bought and sold like a commodity. I get the feeling though, that the money IS the important part for you, and maybe that's why this guide is so important to you. I think that an informational guide is a great idea but including prices/values is the part that I question. If I can't take it with me, why would I care? OK, that isn't fair. Yes, I would like my collection to at least retain it's value, in real money but I believe that would happen anyway, with or without a price guide.
