you can absolutely DIY your own alignment; i've done them myself for years (camber and toe at least).
depending on your technique you can get very close if not spot on to factory alignment, or set your own as desired. My only gripe is the precision is not quite as good as an alignment rack but for most daily driving it's adequate.

you won't wreck your car unless something is loose or you have some alignment way off
