Thank you all for your input, especially Bachus for the detailed info and the Thomann link. They sure have everything under the sun.

I forgot about the Casio px-5s. I bought one a couple of years ago for a church group oversseas. I thought the keyboard action was excellent. Only 24 lbs! The RD2000 is very nice, but 47 lbs. I just can't get over how many choices and values are out there when I compare them with my midi/digital accordions.

If the Nextar's action is very similar to that of the Code 61, I can live with that. Actually, as a trained piano player I really like the action on the Code 61, but I thought organ players may not like it because the action, though not a hammer simulation but weighted keys, feels more like a piano action. I compared it just now with other keyboards and a Technics organ I have. A noticeable difference.
