At my local Best Buy they have both 2-disc Best Ofs...1990-2000 2-Disc is what I see at most stores anyway, but the 2-Disc 1980-1990 I hadn't seen for a long, long time... I almost bought it when I saw it but I need to save my money for the tour
You can still find the 2 CD Best Of at various retailers. I think I saw some at Tower Records too. I'm sure with the new album they have been bringing out their old stock.
