Hi if it's focused clit stimulation you could do no better than the Tracey Cox Supersex Rechargable bullet. It on offer/sale at the moment making it only £12.50 and the savings on batteries make it worth it. It's very powerful, has 3 speeds and 7 patterns. Usb rechargable, and lasts for hours on a single charge. Not that you will need hours, she will be orgasming in minits.
if you like a bit or role play there are a couple of new butt plugs with "tails" which could be fun.
Now for you have you tried the 2 inch ball stretcher? Very soft and stretchy easy to wear, very comfortable (according to my OH) and adds a bit of something different for oral, penetration or solo play.
just a few ideas that are affordable, for most. Enjoy.
