well, what is quality to you. Are you simply talking about a cue that plays really well, as good as any custom cue? Or are you talking about who made the cue.... the name associated with it.
I've seen numerous guys take a house cue from a pool hall, have the shaft taper worked on, had the ferrul and tip worked on/changed, and had the cue refinished and let me tell you... I couldn't tell the difference between those and some of the more high-end customs I have. Those house cues played lights out.
They were various makes like dufferin or what not and were purchased from any billiards warehouse. You can make a decent piece of wood/cue into a monster if you take the time and effort.
