Gary, if key feel is a priority, Roland's are probably your best bet (although many, including myself, can get by pretty well with the T2's keys too, in a pinch), but you want the ne plus ultra of arranger key-beds...?

G70, hands down.

Unless you ONLY want 88 piano-touch, which I find restrictive for organ and other sounds (except piano, actually!), there isn't a better key-bed out there. Unless, of course, you PREFER lightweight, spongy, no feel keys. In which case a PSR is ideal...
