Tom Rapids Pro RP3 filter...thoughts?

No, they wouldn't. There is not a market for all-in-ones. Everything is a compromise instead of having a good skimmer and sump. You do not need a wet/dry and a "canister filter" is nothng more than a media reactor that you can buy for $30. There is really no point because once you buy it, you are at a complete dead end with no where to grow. All-in-ones... in any hobby, are for beginners... after people learn what to do, every one moves to components. It's that way for just about any hobby.
