Congrats! My A3000/16 purchase was also my favorite and like you I couldn't afford one when they were released, but spent lots of time dreaming of one and visiting my local Amiga dealer.
Recently acquired one and installed Mechy's SCSI reader, WD SCSI chip update and 16MB of FAST ZIP, ALL worked amazingly well!
Also found a affordable A3640 V3.2 that worked without incident in A3000 as well, but would prefer to complete the upgrade with a Cyberstorm MKIII anything.
I also hunted for the Ariadne I or II network card and transfer files from my Mac desktop easily and/or download on the Amiga directly.
Enjoy! I am now fully restoring an A2000 and on the prowl for a Tekmagic/GVP 68060 for the A2000.. Giggidy.
