One area of focus could be QuikPak - they manufactured and distributed 4000Ts in North America from the restart of production in 1995 through some point in 1998. Only 2000 built in that timeframe doesn't make sense, especially when you consider there was also a European factory. Back then, the market was small, though still viable. Exponentially larger than today's userbase.
News from that period, especially North American news, will probably yield the best information - Amazing Computing, Amiga Informer, and CUCUG's Amiga Web Directory are probably the best sources.
