Strength

Probably not for less than fifty dollars. A friend of mine is saving for the Sybian or The Rock Box. I can't speak from experience about either of those vibrators though. However, if you want something similar to the Hitachi, I would suggest either The Wahl or a Fairy Wand. I own the Hitachi, Wahl, and Fairy Mini but highly suggest the Wahl. It is the most rumbly of the three and is nearly silent.

I think the Hitachi is the strongest vibe i know of.

I've tried the Wahl & it's not all that powerful for me. It's frustrating/disappoint ing if you're trying to reach climax. Don't buy this one unless you want a back/body massage... This is about all it's somewhat good for, & it's quiet. I'm trying the Fairy Wand next to see how it compares to the Hitachi, which I already own 2 of and I'm not totally happy. I wrote a review on the Hitachi explaining why in my experience, it's not as perfect as everyone seems to think. There are a few major design flaws. Hopefully, I'll have a better experience with The Fairy, which I should have soon.

You want something stronger? How about a sander?

i doubted the intensity would be up to my standards when i ordered it, but when i got it, it was too strong to use on high. so i can't imagine wanting anything stronger XD

Not yet...hopefully there will be one soon.
