If you really want to get the best performance on transients, bass and accuracy simultaneously, the table is somewhat less critical than having the capability for VTA adjustment on-the-fly in the arm and a cartridge that is complimentary to your downstream rig. Even the most minute changes in angle can drastically improve performance. That means you might want to consider what sort of arm you like first and then build from there. Choices include Graham, Tri-Planar and JMW, among select others. The catch is that depending on how "free" the isolation platform is and how "tight" the VTA adjustment, you may have to develop a steady, gentle touch. Also means that you can forget "set and forget". No way to extract maximum performance without tweaking for each side of each LP. Even on the same side, depending on a whole host of variables. Totally worth it, too. You might want to look up some of the archived threads here on VTA/SRA for more background.
FWIW, I had good results with the Rega line in unsuspended platforms and VTA on-the-fly back in the day. Did not have to isolate for footfalls however, so can't speak to that.
