The ones I like are the A3-2T along with the mini B3-3 motors. I love the C5-3 but did not 'choose' it just yet, but if that ever came back, I would definitely be getting those.

Also seen what looked like 'your' version 20mm D5 motor and picked that.

Plenty of others there as well, but only a few of them I would really want as a mainstream motor choice.
