Allow me to disagree. The MM6 is not any better in feel, and you would need to spend twice the price or go with an older used rompler. Plus sound-wise and spec-wise it is untouchable in its price range.

As an all-rounder composition tool it is a great instrument for the price. Most composers deal with acoustic as well as electronic sounds, and the price is right in it's range. Personally, I would save for an M3 (much nicer overall quality), or get a real synth in the PC3 which I happen to have and love...

For what it is worth, I do see the value and need for analogue, but I like the immediacy and variety offered by modern workstations...
