Reading the past posts, I've seen lots of "for sale" ads, where the buyer was supposed to offer a reasonable price.
How does one know what is reasonable? This is collecting, so prices can vary quite irrationally. It's the same with HP vintage calculators (I collect those too): some models are highly sought after and can fetch thousands, some are considered un-interesting and can be found (relatively) cheap.
My point is, how is one supposed to know what is reasonable, when dealing with a limited, discontinued, or handmade collectible? I myself never make any offers if I don't know the "ballpark" of the price, because I don't want to make ridiculous offers.
In the HP calculators community, the collectors compiled a table, with minimum and maximum expected prices depending on model, condition, and so on. Could anybody do something like that for Revos?
