Although I like looking at custom cues, it has been at least ten years since I've had any interest in buying one. These days, I'm more into vintage production cues.
I bought and sold several custom cues between 2001 and maybe 2008. I drifted away from customs and to vintage production cues for three reasons: vintage production cues are usually more affordable; they have a historical provenance that's just as romantic as custom cues are; and my experience has been that they feel and play just as good. The only advantages I found with customs cues are that you can completely design your own cue, and that the wood used by custom cue makers is usually more beautiful. The beautiful wood is the only reason I might order a custom cue these days. I prefer plain janes, and a beautiful piece of wood can turn a basic cue into a stunner.
As for high-end cues, I just don't feel the need to spend all that extra money on inlays.
