I still have a D110, but i've not used it in many years. It can sound genuinely good. Perhaps even great. But it's such a major pain in the rear to program, that it left me feeling cold and uninspired. I didn't have the patience to persist with it. That said, I never did try it with the matching hardware programmer (Roland PG10). And I expect some software programmers must exist that would make it rather easier to program too. But without a more intuitive way to program it, I think it is about the most dull bit of kit I have ever owned.
I have to respectfully disagree the U110 and 220 are very different. The 110 had cool expansion cards but no reverb and was very noisy. The 220 was cleaner and more polished and still to this day has a workable piano, gorgeous strings, and one of the best sax's of all times. Plus 2 expansion slots I think, maybe just one; can't remember.
The D110 is a great piece but no dedicated performance mode which means you have to layer sounds by putting the tones on the same midi channel instead of having a dedicated layer mode. FYI, my D-20 was one of my most beloved synths and provides many fond memories.
I am real picky about condition so if the units are mint by them now! They are still very good.
