Ian, my arranger is the PSR-S700. My synth is the Roland Juno-Di. I've moved away from the all in one synth workstation and now use my Juno-Di with a DAW. It's also used as a midi controller too. The Di covers A LOT of music and coupled with a DAW, it's a great composition tool.

I also use the Beat Thang Virtual for creating hip hop and other modern styles. The Di makes a great midi controller for this. Plus I still have my trusty old Roland RS-70. We're attached at the hip I guess. I think I've had that synth now for at least 10 years. Its got a broken key that's taped down, and I still use it.
