Why not get a (gasp! shock, horror!) a workstation to go with the E80? Plenty of good 76 key choices there, unlike arrangers........

Perhaps a Motif-ES would give you a different set of sounds, and there are a few things you can do with the ES's arpeggiator that you can't do on an arranger. Or possibly a Triton Extreme 76..... possibly the better choice if you want to sample much.

If another set of choices of styles was what you were looking for, though, I think you may have made a mistake trading your T2 unless you have managed to convert any of your T2 faves to the Roland. (Contact me if you have )
