I got a good one at Target a couple of years ago. It was a National Geographic one and came in a hard, yellow plastic storage case with all of the accessories you need (slide plates, etc.). I think it retailed for around $40, but I picked it up on clearance at their July toy sale for $12. I do reccommend it!
here is a similar one (I know it is out of stock, but wanted to show you what it looks like)
I think this is the microscope I will be getting. Thanks for info!!
The microscope on the Amazon sale page is not worth the money. My dd had one just like it several years ago and it was worthless!!
