Bubble King or Reef Octopus, sizing ... ???

[MitchM]

I have a BubbleKing Royal Exclusive 250 external.
I've had it for about 6 years. Expensive, never had a problem with it, enjoy working on something that's high quality.
I purchased mine from Wai's.
It looks like there is quite a price difference between a Reef Octopus and a Bubbleking, so you'll have to decide that for yourself.
