While I agree with you that SCSI is a far better standard when it come to speed on the Amiga when compared to IDE, you have to remember a couple of things though... 
Firstly SCSI HD are obsolete, no one has manufactured SCSI HDs for at least the past 2 years now...
Secondly I reckon most folk will be using a desktop A500/A600 or A1200 in comparison to the amount of folk using Big Box Amigas (A3000/A4000 etc..) and in which case IDE is the easier route to go...
Gotta disagree with you on your comment that "FastATA sucks the life out of a CPU" on an 030 or 060 accelerated A1200 either loading or saving big files for example an 8.2GB DVD ISO there is no real slowdown in system performance that prevent or hinders you in any way from doing something else at the same time...
Not so true for the 4xEIDE Buffered Interface but then it's nowhere near as fast or good as the FastATA boards...
SCSI is fine for big box Amigas but when the remaining stock of SCSI HDs run out then you are going to be limited to second hand/ used HDs in future but the same will soon become true for IDE HDs as by the end of this year all the major manufacturers are phasing IDE HDs out too in favour of SATA... 
Well, scsi hard drives are still manufactured today. Just because a person uses a A500 or 1200 doesnt mean he/she may not also use a blizzard with scsi.Were were talking about better not easier. There are thousands of servers world wide that use the older 68/80 pin drives. these are backward compatible.A quick search on ebay alone brings up tons as well as pricewatch and other places.even if they were'nt making them i have solved this with the 50 pin scsi to CF card readers which allow you to use Compact flash cards as scsi hard drives with no adapters.
I never said you couldn't do stuff,i was meaning the fast ATA uses alot of cpu time,especially in the higher modes..try it,kick it up in the higher pio4 or other modes and see what it uses on large transfers. This doesn't bother you because you haven't ever bothered to have your machine on the net. I actually use mine everyday for internet stuff-its not uncommon for me to be downloading gigs of stuff while browsing and such or .Now if its just gaming,then load times wont matter much.Try the blizzard 1260 with scsi in synchronous mode(up to 10MB/s) and compare the results with your fast ATA.
the 4x buffer boards of course are not worth mentioning,because they still rely on the stock ide.
SCSI is fine for ANY amiga,it really shines on the lower spec machines.
