I have a couple of ideas for you that could help... but let me say up front, Eheim would be the best way to go.
Because this will be a goldfish tank, I would strongly suggest you work with a good filter that allows the addition of extra filter media as needed (carbon, nitrate absorber, etc)
The first one is made by hagen, it's a powerhead with a filter "instert" that connects to it. Here is the powerhead: http://www.drsfostersmith.com/produc...44&pcatid=4644
Here is the filter attachment: http://www.petstore.com/ps_viewitem....roduct=HG10575
My preference, and yes, I've used both of these in the past... Eheim makes a wonderful internal model that allows for carbon, sponge, etc... and has adjustable flow to it. http://www.eheim.com/pickup.htm
Because you're keeping goldfish I would get the biggest filter you can, plan to "over filter" the 30 gallon to help with any waste issues as the fish grow. The only drawback on both of these types of filters is that you don't have the ability to add extra carbon to either of them if it's needed.
One other option, though the flow isn't adjustable there are diffuser attachements to work with, and it's also about the best internal for something like you're setting up: http://www.eheim.com/aquaball.htm
I've used these, also... and because you can add more baskets according to what you need, it's more effective than most others.
Hope this helps!
