I just sold my JV 1010 and bought a JV 1080. I picked up the 1080 for $550, which in my opinion makes it a deal next to the difficult to use 1010 for about $100 less (new). It has 4x expansion vs. the 1010's 1 additional slot, and has a complete user interface that is VERY easy to use, compared with the JV1010 (Just look at the amount of posts on this board that are questions dealing with the 1010). In fact, unless you never disconnect the JV1010 from your computer and have more than 1 MIDI port (you can't use a sequencer like Cakewalk while editing performances/patches etc), and unless you are happy with the fact that once you turn off the JV1010, everything you've done is ERASED, I would skip the 1010 in favor of the 1080.
Brought mine home Thursday night having never used it before, and resequenced our entire set list and gigged with it this weekend. I would highly recommend a used 1080!
