Compound or dissecting microscope for plankton?

[Piker]

As the title states, I'm looking to get a microscope for phytoplankton and zooplankton. I'm on a budget. Right now I am more focused on phytoplankton, but I will be using it for zooplankton as I progress in the hobby.

I'm not afraid to go bigger, I just don't want to spend too much just to verify that my cultures are pure and to do rotifer density counts.

I'm currently considering a compound...

The Swift brand compounds are very nice.

Oh my gosh, I was just looking at that microscope and I thought I'd come back here to see if anyone had replied. Thanks Big G!
