Personally, I've owned two sex toys: a hard, plastic vibrator which didn't take me close to orgasm when used inside or on the clitoris, and a silicone (gel-like) vibrator which not only make me orgasm within five seconds but made me squirt all over the bed as well! That was not pleasant at all because it was too powerful. However, I also used this toy anally and I found that I much prefer an*l penetration over vaginal penetration. Each products were only $20 and I enjoyed neither of them because of too little or too much pleasure.
My advice from the little experience I have is to don't stop at one toy! You may not like the first toy (or two or three or five), but that doesn't mean you won't like any toy. Sex toys are made from all sorts of material and can do more than just vibrate or stimulate only one area of the genitals but many. And don't rule out an*l! It can be so pleasurable even if it sounds uncomfortable...you can be surprised at what you like.
It sounds like you've received some amazing advice, but I wanted to throw in my two cents as well.
