I have actually discovered a PSX bluetooth controller in China that was initially made for windows mobile devices. The Bluez-IME developer got the controller to work relatively easily because the controller was modded after the base of the BGP-100. With Bluez-IME the controller works with literary all emulators including FPSE.
It's quite decent actually, no delays or anything like that and the battery lasts for a few days of moderate usage and can be charged with ease via microUSB.
I posted a video today on youtube at http://www.youtube.com/watch?v=jLB7zyWrVnY
. If people are interested I could probably probably post them for like $30 USD + shipping (probably around $10-15 for Europe/USA) next time I go to Hong Kong.
