We got a Leapfrog Explorer Smart Globe. No problems at all, we love it! It seems very robust for young children, and I wouldn't call the stylus delicate. I think my cats even tried chewing on it... It still works great.
I must admit we do use our fancy floor globe more though.
My Amazon history says this is the one we got, but ours was only $99. It looks the same except it is the green one pictured:

It has 174 good reviews, so most people also must love theirs! If you search this forum, I did find a link where you can get one for around $100.
The Leapfrog one doesn't have the cool USB feature, but looking at the reviews in this post and on this page, sounds like some others have had problems with that feature or something else:
