I have a PL1770GP , PL1880NW and a PL1880WN.The fact the PL2260 is a neck
through and has shark fin inlays DOES NOT make it worth $1500. All 3 of my Pro-lines are
in 8-9 condition and I didn't pay anywhere close to $1500 for any of them. Heck I don't
even have $1500 in all 3 of mine combined...I agree with toshiro, $600-$700 max
and that's if it comes with the original small/grey case.
The 2660 is nice, and somewhat rare, but it's not a collectible, IMO.
Pro-lines ARE getting highly sought after. They don't bring the high
dollar value of the Jems etc. but if a PL1880 or better comes up on the
bay, people will "fight it out". I'll say this, quality wise, Ibanez doesn't
make much nowdays that even comes close to the quality of these
