Thank you everyone for your recommendations!

Well, so far the AT440 seems to have the edge... I'm only wondering
how it will react to some old and not-so-clean LPs. Aren't high
precision carts more sensitive to scratches and dirt? Maybe I could
try to find another TT and have one for crappy LPs and another for
mint condition ones...

Anyway, for the moment, the old M91ED is working great for the money
I've put on it... And it's not a bad cart, from some posts I read in
the archives.

Thanks again.
