do any of you experts have an opinion of what a mk1 supergraph would be worth, in fair condition. I know they are rare, but maybe so rare that there isn't much of a market for them? there were ~ 100 made, so in terms of rarity its about the same as my mk1 b jetgraph. But in all the blogs and internet sites they talk about the supergraph as the grail, " unicorn" etc. Anyhow would really appreciate any thoughts you might have on the value. thanks
