motm or doepfer

[gur milstein]

helo every body.
i read the motm catalog and price list and i'm a litele bit confused,
how come the price's of the motm are higher then asembeld modules
frome doepfer.
for exemple the ring modulator frome doepfer cost 100DM which is about
80$us <1996 price about the same today>and the motm ring modulator kit is
about 130$us,
are the deferent is because of sound quality cv inputs or what ?

thanx
