Hmm... Good luck. That's the best strategy. LUCK.
Or paying an insane amount to liberate a bulk of them from one of the IC suppliers that has them sitting around a storage unit somewhere. Most of those places start at 20-50 unit minimums with a per unit price of >$100, which prices it right out of our market, even if you could get 19-49 others to buy into the idea...

None of the Amiga suppliers I've tried currently have any. Even though most have them listed on their websites still... That's a complaint for a different thread.
