Those bikes were, IIRC, really popular - you aren't missing on a once-in-a-lifetime deal by passing one.
Cannondale CAADs from that period were good enough to be professionally raced (by Saeco) as late as the early 2000s. Bianchi, IIRC was a fairly late user of aluminum as well. I think a few pro teams were racing steel as late as 2001 (I recall an article featuring the ill-fated Mercury team complaining about racing Reynolds 853 bikes that year).
I think the last steel bike raced "in anger" by a top level pro team was CSC racing the Cervelo (Super)Prodigy at Paris-Roubaix '03, though a Continental British team used steel Genesis bikes (Reynolds 953 stainless) very recently.
