The bow looks to be the 1st Titan in the series.
I consider the Titans to be one of the better bows on the market, that being said $400.00 with a case etc. is right in the ballpark of the markets today.
I have been researching crossbows for a couple of years and IMO the Acu Draw is the best the way to go for an even draw.
Of course the sentimental value for prized possession of a loved one is worth a million bucks.
Best of luck on the sale.
