For me I have always looked at the high end router tables with lift. I wont say they are useless but for what money they cost you could buy yourself a large tool like a 17/18" bandsaw. My router table I use is 20 years old and not much more than a chunk of MDF with a hole in it.
Biscuit Joiner - Face it, the only reason most of us own one is because Norm used them.
Saw Blades.- Never used a high end blade but never seen the need to use anything else than my $45 Freud.
