I've just ordered a forge TIP and want to install a catch tank before I plumb nasty oil vapours into my new TIP. I'm just wondering who's tried them as I know some have but they all seem to be the expensive ones. Has anyone gone cheap and found it to be ok? Also, anyone had problems with these or with venting to atmosphere as ideally I don't want to put it back to the TIP at all, I'd rather vent to atmosphere. Any thoughts?
