I just picked up a Buddha Flash recently and it works great. I have an Amiga 4000D and just wanted to be able to add more IDE devices. I attempted to hook up an IDE to CF adapter but was unable to get it to work. Of course, I never tested the IDE to CF adapter in another system so the CF adapter I have may be junk.
All-in-all, I am very satisfied with the Buddha Flash. All the documentation is on the floppy. The floppy itself is a High Density disk formatted as Double Density. Because the A4000 had a High Density drive, I had to use an external floppy drive to read it. The disk also had an error on it but I contacted AmigaKit support and they sent me a link to download the floppy files.
I hooked up a DVD-ROM, Zip-250 and Hard drive to the controller and it works great.
Good luck!
