I tried a few and you have to prepare for big tolerances. So you need a adjustable clamp design to fit a motor mount on it, because some are bigger some are smaller…
Also make sure to check the material, some make strange, soft alloys which bend the first time you step on the board.
Third point is pivot cup and bushings - most of them are just pure shit and you should replace them as soon as you get them.
These are the points to check. If the material is good and you don´t expect high precision and replace the soft parts, it might be worth a try for a cheap solution.
