/u/CunningLogic uses this scope with 10x eyepieces and swears by it. You could get it directly from AMScope.
I went with something a bit more expensive and got ahold of a really nice used Nikon with zoom.
When buying glass, you usually get what you pay for so it comes down to how much do you want to spend?
What do you want to see in particular? You won't be able to see nosema with a dissection scope.
Edit: You could also consider a USB scope if frame rate isn't a concern. They're incredibly cheap these days.
I've spent a lot more for lesser quality, this is servicable.
