That's a very important point, which the OP should really bear in mind. I had the JX-10 for about a month without the programmer, and it was just no fun at all to edit -- and without quick and deep editing, the JX synths are very underwhelming. Then I got the programmer (traded a Mopho for it

) and basically "discovered" the depth and power of the synth. I don't think it's an exaggeration to say that an external programmer (whether PG800 or one of those Behringer units) is
essential to the JX series.

Remember that the Jup6 is a VCO synth, and so if OP is really looking for that classic "Roland DCO" sound, the Jupiter might not be the answer. I've never played one, but the internet chatter suggests that it's a very raw, aggressive synth, which the JX series most definitely is not. But again, for soft and warm, the JXs are ideal.
And don't forget about the dramatic price disparity. For the price of a Jupiter 6, you could get a JX-10 (or 8P, or MKS70) AND the programmer, and STILL have hundreds of dollars left over (with which you could get a Juno 60/106 and then *really* have your Roland DCO base covered 8) ).
