I have the EB-1150 and I still love it. I also miss my old REB-1100.
Anyhow, that weight doesn't seem too bad to me. I've held these older ones for a long time. The page turning thing is a big issue though. The JE-100 has a noticable delay in page turning for such a well-made device. It was actually worth putting up with though.
