I'd agree that the bang for the buck is pretty low with gen crystal and bezel. Single side AR - whether it be gen or not - is so subtle that I could never detect what it is. If the crystal by itself is coming at a price that is lower than a rep sapphire + aftermarket AR job, then obviously it's worthwhile but probably not otherwise. The JF case is nice to have, but of all JF parts the cases do seem to be the most available / least sought after. They come around from time to time, unlike the JF CGs. And finally, on the bezel, I'd also say it's not a good value. Who can differentiate between a gen and JF or even rep bezel?
