I am a huge fan of LELO brand sex toys. They are made of the highest quality materials, and while they are pricier than $50, they are THE BEST. I would especially suggest these two: http://www.amazon.com/LELO-Luxury-Rabbit-Vibrator-Purple/dp/B005FG92IK and http://www.amazon.com/Lelo-282-Gigi-Deep-Rose/dp/B000TGIVLK
I have both, and let me tell you, they have not let me down!
Okay but Lelo makes such quality vibrators. This guy is spot on & literally i cum in less than a minute: Lelo
