Not voting on the products but the categories I went with the Lulu or the Renew. I'd go with something that is good for both internal and external use, and also something that can be used externally during intercourse.
My top recommendations would be the Envie Ripples
(powerful, lots of settings, versatile), the Diamond Fairy
(easy to use, quality, cheap, eats batteries quickly), the Picobong Zizo
(AWESOME toy, great settings, a bit expensive, very quality), the Sinfonia
(quality, great if you like a bit of internal stimulation and a lot of external), or the Harmonia
(for those who like internal stimulation a bit more than external.)
