first of all, i'd like to point out that the subject title is misleading - to get "ripped off" on Ebay means either the seller doesnt send the item, or describes it wrong. You offered the seller $860 for the item, totally your choice.
Next, on the issue of "did you pay too much", well maybe a little - brand new CIJ Jaguars go for around $650-$700, and I'm not aware of any differences between the 1994 models and the current ones.
But then I do know the current CIJ Jags arent the highest build quality, and come with bad pickups, so maybe the early 1990s ones were better.
The seller also lists "rare" in the item description, not sure why a sunburst jag is rare, maybe he just means its cos its a 1994 model?
But anyway as said, if its a decent guitar who cares what you paid for it? I've paid too much for a few things on ebay - ts just one of those things 😀
