Come on down out of the nosebleeds. 8.0's are perfectly acceptable (at least to me) and are far more affordable than all those high grade copies and still present very well.
My run averages about 7.75, (Excluding the 83, which I'll wait awhile for till the current fervor is over...) it costs a small fraction of what it would have cost in 9.0/9.2 average. Overall, I'd hazard a guess that it would be at least 10X as expensive and even that may be conservative. For instance, I cannot imagine what one of the 9.4 84s would go for if they ever hit the market.
A 9.4 just hit eBay:

Restored, though
One of the owners of an 8.5 ow 84 is entertaining offers starting at $2,467 on Heritage...
Kevin's been selling his high grade JIMs on eBay (#6 registry set)(I'm the happy new owner of his #85) but now I'm broke...I'm relegated to the bench with the Clink and Heritage auctions about to go live...I'll cheer you on, though.
Even that is impressive. There are only three 9.4s total, including this one restored copy. I suspect we won't see one of the blue 9.4s for a very long time. Captain Tripps has one of them. Frankly, it's possible that there is only one blue 9.4. That one may be a resub.
