While plenty of people will say that one good vibrator is all you need, I'm of the opinion that it's better to have a wardrobe full of sex toys. Sometimes you want the power of a wand vibrator, and other times a simple bullet will do. And since no one vibrator can do it all, having more than one on hand ensures you'll never have to miss out on exactly what you're craving. But if you don't have a spare few extra hundred dollars to shell out on assorted sex toys, you'll be glad to know many of the best cheap vibrators work just as well as their more expensive counterparts. And luckily, Amazon has a whole host of wallet-friendly vibes for your masturbatory pleasure.
The most important thing to remember is that a good sex toy will be made of silicone, which is safe for use both on and in your genitals. If it's not made from silicone, you might want to be wary about putting inside of your body, since the skin in there is extra sensitive.
Many of the cheapest vibrators also tend to be battery-operated, which can wind up costing more money over time than investing in a more expensive vibrator that comes with a charger. It's up to you to weigh out whether or not the initial cost overrides the long-term expense of buying batteries over and over again.
