How about Dimage A2
Although its an old model, It has a mechanical zoom (wire by frame) lens with 7.1x zoom. I have both A1(BP-400 grip) and A2. I saw only one shop (2nd level Sim Lim) is still selling it. If you want, can go check it out together with the other potential cameras in mind.
A200 (support remote control) also can consider, but it does not have a grip like A1 and A2...
