The keyball and trackball manuform variants[0] all seem great to me. My one issue with them is that the thumb clusters are not symmetrical.
I don't have money for a svalboard[1] so I opted for an interesting variant found on AliExpress[2]. Unfortunately the delivery person threw the package on the ground[3], so my integrated pointing device project is in limbo until this curious planck-like keyboard arrives[4].
