I have one of the new MRC OceanForce 200s. It is very similar to the Octo Extreme 200. I just upgraded the pump on the MRC to the Sicce PSK 2500 which comes standard on the Ocotopus. I don't have any numbers, but the Sicce puts out a much greater level of foam than the standard pump on the MRC.
I ended up going with the MRC because they were local and I thought the gate valve gave me more adjustability. I wish I would have went with the Octopus as the choice of pumps on it performs much better than an MRC. I could have added a gate valve for $20 instead of $150 for a new pump.
