Well I got one, I think I paid $25 shipped for it off ebay because it was broken (Didn't read discs and tray didn't open) but I was able to fix all that and its working perfectly except the fact I can't play DVD based games until I find a JAP DVD or HD utility disc to install the driver (SCPH-10000 & 15000 don't have a default DVD driver) Ive still yet to determine if I can use a US utility disc for it though. BTW u need a ORIGINAL utility disc for it to work, backups will not work due to it being magic gate encrypted. Also alot of emulators do not work with it, for example - SNES-Station, Pgen, PSMS, the Atari emu, etc
SMS, HDloader, and USBAdvanced also do not work.
Homebrew games and Neo Geo CD is what I've found to work.
Modchips off the top of my head that work for it are:
DMS3 (any version), Messiah and I think Messiah clones, Ghost 2
V4 MI w/500gb HD & custom HD fan
V9 CC 2.0 w/300gb HD
V4 DMS4 Pro w/250gb HD
V3 CC 2.0
V12 Modbo 745 /clear case
V0 SCPH-10000 JAP w/ DMS3
