got a prism and it works well enough for me. I do have a relatively light bioload though.
anyways, the thing with prisms is that they need quite a bit of fiddling. I put an airvalve on my airline and it worked MUCH better. It took me a couple of days to find the right balance between water flow and air flow without losing the siphon while still ending up with the foaminess.
If you have the cash get a better skimmer, but on a low budget, I see nothing wrong with it.
