For anybody interested in performing CRISPR in their kitchen with $150 worth of pre-packaged materials, I would encourage them to take a look at The ODIN. It is a kit to get you started, and it comes with tutorials to take you all the way from knowing nothing to being able perform CRISPR and understand what you are doing.
