brookemarie,
I bought the second one not too long ago and it was very top heavy. I returned it right away because it kept tipping over. There is a more heavy duty one that is about $40 on sale for half off that I got a long time ago. I love it. It was well worth the cost and I haven't had to change the bulb yet. Don't know about the first but I'd shy away from the others. You might also check Big Lots if you have one near you. Mine has a floor model for about $29 and a small table size one on display but they never have the small one in stock.
Good luck,
