Perhaps the Uma or Getaway Luxe?

i think both are okay for g-spot stimulation and they're not super strong.

Anything a little less expensive, perhaps?

I would suggest these as a possibility:
Mood Passionate. You can check out my review if you want.

maybe more so this style
Sphere

I have this and recommend it, I have a review of it as well:
Pretty Pearl G-Spot

I reviewed the Waterproof Silicone Bendi G but the texture may not be something enjoyable for a beginner so I'm gonna suggest this instead which is similar to the more expensive We-Vibe 2 and 3:
Groovy Chick

I also liked this but haven't reviewed it but would recommend it to anyone:
Gino


But those are my suggestions for under 60 bucks (most are on sale now though)

I always recommend the original bNaughty egg -- but it won't get you anywhere for internal stimulation. Fun Factory's Layaspot isn't super strong, and I like the shape. link It's only for external stimulation, still, and might be more than you want to spend.

Something like this might work for both: link

I've used this one. A little weak for me but perhaps good for you: link

All of these vibes are 60% with the code "VIBRANT" (discount will be applied at checkout). The Roulette line comes highly recommended ($30 with the code!), and the Seduction (holiday edition, not the silicone one--$12 with the code) is awfully popular. Evolved is generally a good choice if you're not looking to spend a fortune. I haven't tried any of these myself, though.

Happy shopping!
