For silicone dildos - you can't go wrong with the Vixskin line. They are not cheap - but if cared for properly they will last a very long time. Luckily they come in sizes from the very small Spur to the gigantic Outlaw. We have the Johnny, Maverick and Outlaw - and love them all even though the Outlaw only gets used a couple times per year.
For vibrators our favorites come in two categories - wands for clitoral stimulation and insertables. For the wands we find the Mystic Wand to be a good choice - but there are many similar toys to choose from. For insertable the G4 Big Boss is her favorite. We also use Mona or Uma for g-spot play during oral. Neither are strong enough to create an orgasm - but they are good for getting her ready for a dual-orgasm (vaginal & clitoral together).
