Greetings, Deaconjohn & welcome; I would say (as a Triple Omega owner), that the price is a bit high. Of course, from a collector viewpoint, this is a 'pre-pistol grip' bass, where the later models, like mine, have a slightly different upper horn (if that matters to you). If I were to sell mine (a 2003 5 string model) today, I would ask somewhere in the neighborhood of $8K, and probably take a bit less. A new version of my bass would run $14K (via the quote generator here).
That wood is spectacular, and it is a 4 string, but I still think a 23 year old axe should command $4.5K to $6K in the real world, depending upon condition.
A Triple Omega is not for everyone, but the sound from the 11.5 lbs of Mahogany/Maple/Purpleheart/Ebony or whatever combination of woods the bass is constructed of will make you smile for years on end.
(Oh, and the larger body style makes for an absolutely perfect forearm rest, if you're a non-pick style player) :-)
Good luck to you.....
Chris
