Because of the internal expansion possibility, I was going to grab a Wicher. However, the availability is actually low, I found many websites report that the A1000 did not work well with the wicher. Also, by the time one upgrades to 3.1 roms, and everything else the price ends up being slower overall and double the price of the ACA500 Plus, so last week I ordered this board. Regarding upgrading the Amiga 1000 agnus to a 1mb Fat Agnus, I would like more information. Nevertheless, good to see you are getting this working...I would love to see a youtube video showing your setup and such...cheers from Canada.
