Not sure if the fishsticker post is a troll, there's a far better bow:

The fishsticker is absolutely not worth farming/buying as you can get a ~410 bow from either of the first two instances, a ~409 gun at level 80, a 425 gun at 82/83 and a 405 bow fairly early in your questing.

I mean if you like the model or whatever and don't want to buy it fine, but it's certainly not a worthwhile item to farm.
