hello alexander,

filters are always a matter of taste.
in my opinion the a124 is a good choice for an unique sounding
filter, especially if you like a bit of distortion and don't
need a self-oscillating filter, but i'm not a fan of the a121.
is price and space a big issue for you
if not, i would wait for the a107 instead of buying the a121.
the a108 is my favorite filter, but it has no highpass output.
it is worth a look, if you mainly need lowpass and bandpass.

best wishes

ingo
