Price is an issue.
Cheap toys can be irritating to the sensitive skin of the genitals and can have an unpleasant ordure.
Silicone is the best choice. If you can't afford a good quality toy, use condoms on the toys.
I suggest that anyway clean up is quick and no worries about skin irritation.
Don't get too cough up in all the bells and whistles. Start off simple with something for clitoral stimulation.
