4 GPM 6' head and around 7W power dissipation. £69 in the UK.
Have asked them for P/Q curves and NOISE level Have an Eheim 1048 at the mo, which is totally silent.

Still more expensive than a MCP650 though, you can pick one up for £55 (inc vat), or maybe less if you get one shipped over from the US due to the low dollar.
