This isn´t exactly what can be called a "large frame", it´s probably an eighteen or nineteen inch frame, but Spesh did produce frames up to 21.5 or even 22". One question regarding the bike you saw in the bight; did it actually SELL for that amount of money or did some guy try to make an unreasonably amount of cash out of it?
To give you an idea what these Rockhoppers are worth, this bike is up for sale since a few months:http://www.ebay.com/itm/Vintage-1988-Sp ... 0531248471
Really lovely condition but 800 US dollars are obviously out of range.
"Moderately scratched" you should end up in between 60 and 150 bucks depending on the quality of the photos, the shipping conditions and so on....
edit: i did overread "Stumpjumper", add 30 - 50 and the bill fits.
