Hi Andrew,
Im going to go against the grain here, and recommend that you dont get a
basic system.
Doepfer modules have moved on a lot since the BS was put together, and i
believe that youd do better selecting your own system, and taking advantage
of the more exotic modules now availible.
You can also leave some space in the case, and then when theres another
module you fancy (there will be for sure) you dont have to get a new case
too.
I know at the beginning it can seem daunting, but if you slog at it, and
then post your suggestions here, then you can make sure youre not making
mistakes.
I personally wouldnt recommend the mcv or the a190/191s, but i know others
have been getting on fine with both. In my own system i use a Kenton.
