I mangled my front derailer somehow on my 2002 Marin Bobcat Trail. It has 3 chainrings on the front and 8 sprockets in the rear.

The front derailer is a shimano Acera. It is my understanding this is a crappy derailer and I see them for cheap online. My seat tube is 31.9mm.

What is a good derailer for me to get? I beat my bike up pretty good doing fire roads, single track, some ramps and obstacles etc, I want something decent but don't wanna break the bank. Will any derailer fit as long as it is made for 8/9 speed and 31.9mm?
