I had bought one in Sept 2008,from AmigaKit, and installed it for about 2 hours in my A2000. I do not know what the problem was, but it cause my A2000 boot in OVER 5 minutes. I then removed it and it was back to less then a minute. Because I could never find a proper manual for it (it was the Phoenix edition), I then immediately sold it on e-bay, never looking back. If you do a search, you will see a lot of my posts over this and the fact that no one could ever produce or find a real manual for the Phoenix (although a lot of posters put up imaginary links to the so called manual, but if you look at the link, you will NEVER find one) I got really frustrated with the whole experience. Trust me, stick with the Scsi and you will have no issues.
