An Xbox Elite controller equivalent for PS4: (Destiny)
The SCUF Vantage has just been announced.
It looks great, and I've heard good things about SCUF. Price is steep, though: $169.95 for a wired version, and $199.95 for the Bluetooth version.
I just about bought an Elite controller the other day, but rumors of a remodel being announced at E3 made me hold off. Although the rumor also states that it will have a rechargeable battery rather than using AAs, so I'll have to see what the improvements are and if they're worth that trade off.
