Well I was going to say around $250.00 but a quick search shows these superfines going from $250 to $350, with the higher end prices little used condition like yours. So I would say it is fairly priced.
I had a Rocky Mountain series of that rod as my first fly rod and I caught a lot of fish with it. That 7'-9" length in a 5wt works very well for small to medium size creeks/rivers.
Took your advice and lowered the price a bit.
