The most common types are costar, cherry plate mount, cherry PCB mount. Whether and which you can get will be decided by your plate and PCB. However, some are compatible with multiple, so you can choose. Costar works pretty well, but people find it annoying to attach/remove. Plate mount has a bit more flexibility in terms of installing/uninstalling without desolder (they can be installed from above the plate). I prefer PCB mount the most, but they have to be installed on PCB before attaching plate.
Quality stabilizer kits aren't cheap - Durock or ZealPC are in the 30USD range, but IMO if you want stabilizers you may as well get good ones.
