Wow. JimmyD is a tough act to follow...but here goes.
I was recently on a F-30 quest and saw basically the same thing that tommym is suggesting above in terms of price range, maybe a bit higher.
Today on ebay, the lowest price I could find on a used F-30 was $1,299 BIN. There's a pretty '82SB for sale at $1,350.
I chose a different route, and may live to regret it. I offered $600 for what could be a train wreck of an '72 F-30NT, which is being shipped from Vermont today (delayed due to the Polar Vortex).
It has a lifting bridge, a bit of top seam separation below the bridge, and a 2-3 inch crack on both sides of the upper bout (both well away from the neck joint), neither looking too awfully bad, but there nonetheless. It had been left in a closet for nearly two decades, according to the seller, after a teenager abandoned it for other pleasures. To top it off, it is sitting in a dreadnought case. Sad, forlorn, downcast-looking thing, calling out "Save me from this closet!" It needs someone who can appreciate its internal beauty.
The prayer I am throwing out there to the "Lords of Guild" is that the neck angle is OK. We will see when it gets here.
It is possible, if I mutter the secret incantation (how does it go, Jimmy? "Prana prana prana"?) and spread just the right offering into the case, that with a little humidification, a bridge reset and a few cleats on the cracks, that the Lords of Guild will smile upon me, and find me worthy, for maybe an investment of only $150-$200 in luthier love. If so, good deal. If in need of a neck reset, probably not, and probably going back to Vermont.
Stay tuned.
