I've been looking at that Tokai because I want an explrore and '82 is my birth year, but I'm not sure, most of the ones I've seen are under £1000, I'm about the buy the same model from 1984 for £600 in black from Tokai Finland. I guess the tobacco sunburst makes it a rare, more expensive model as I've not seen any other ones in that finish
As for Edwards explorers, there are some on the ebay but they are very expensive. Try searching for a used model and you should be able to find one in your budget, there is also Grassroots explorers available
