Did you pull the trigger on this one? Was it the Comanche or the regular model? (I actually prefer the look of the latter, though the former may be more collectible.) A nice guitar either way.
In perfect condition, I probably wouldn't go higher than $350; with some wear, maybe $250. Another $50 for the original hardshell case (in good shape). If it's what you need & sounds right to you, that might bump it up another $50-$100.
