Avast Marine Porthole: is it worth it?

[ColaAddict]

I'm getting into reef photography. Is the porthole worth getting? or can I take just as nice pics using a regular acrylic top down viewer box?

Best $50 I've spent for a piece of photography equipment. My flickr photostream is filled with pictures I've taken with it: Flickr: ..:.. EZ ..:..'s Photostream

It's pretty awesome. I love the colors and views I get from the top.
