Menacer light gun any good?

A local store is selling these brand new and boxed for around $20. Is the gun any good and does it work with any other games than the ones that come with it? Am i better off getting the gun that comes with Lethal Enforcer? I'm assuming that the Mega CD version of Snatcher doesn't support the Menacer gun...
I never cared much for the Men-ass-er, but for $20 new... it's hard to go very wrong. It should work with all Genny/SegaCD light gun games except the Konamis.

Speaking of which, I didn't have much luck getting the Justifier to work with ALG stuff, but it worked great with the Konami games - LE1 & 2 + Snatcher. Snatcher with a Justi was too sick.
