I use one in league every week as I'm there to enjoy myself, which means being able to take my eyes off my cue during the night and not be all stressed about it. So my custom cues are for home and tournament duty.
I'm happy with the playability. Mine has a long pro taper but my understanding is they don't all. So make sure of what taper you are buying. The workmanship is OK, nothing great, but that's not why I bought it.
I wouldn't spend a lot of money on one simply because the market is dictated by the price of his Ebay cues. The good news to that is they're only about $150+- and there is a market for them so if you ever want to flip a used one you could probably get $75 to $100 for it.
