I really like it. I had wanted the Moog Modular and the ARP 2600 for a while so I jumped on this deal and I am not disapointed. I am finding the Prophet a hoot and the Jupiter, SEM and CS80 are all good, I don't like the minimoog as much as Minimosta or Monark but its still decent synth.
The Wurlitzer is OK, I probably would not have bought it on its own, I like my Scarbee A200.
I am not too much into drum vintage machines but the Spark Vintage dose have a certain "punch" that seems to be lacking in many of the samples/emulations out there.
The Moog Modular is the only one I have realy started programing from scratch, while the interface would be better if it were bigger I find it useable.
