I purchased a Peco set to learn how it is done, and had no problems. I incorporated an omega loop in the linkage to reduce the degree of precision required in the adjustments. However all the separate circuit boards (Servo control board, 4 x frog juicer boards and one DCC board ) is a lot.
I then purchased a Signalist SC2 (see Suzie's post # 10) and sourced servo motors and mounting brackets and servo extension cables on E Bay at a fraction of the price of the Peco set up. Again no problems with this arrangement.
One of the problems that the OP had was working below the baseboard while trying to set up and adjust points that are mounted on top of the board. In my layout design I anticipated such access problems (from painful previous experience) and arranged for my pointwork to be on a separate piece of 18mm ply roadbed (slightly longer and wider than the pointwork). I worked on this board on the comfort of the workbench, then fixed the board in place when all was working and aligned adjacent track to it (rather like a baseboard join in a portable layout).
