I've never met a Roland style that DIDN'T play OK in my G70. So that makes it the same for E50/60/80.
Thing is, most of them call up the legacy sounds, so sound pretty similar. But as I keep saying, the Makeup Tools section makes it a snap to convert to the newer sounds and kits, and easily adjust them so they sound their best.
What was too bare-bones about the E50? The E60 is essentially the same, but with a good 76 (not as good as the G70!) and the D-Beam (which I use to easily drop to Bass & Drums in a piece, but has many other uses). It still has most of those V-Drum kits, which I find to be one of the most significant improvements over my G1000... (did I miss it, or have you yet to say which Roland you currently have?). You could probably pick one of these up VERY inexpensively....
