Skimmer/sump advice

[mseepman]

I currently have a 70 Gallon mixed tank without a sump. I use a "very crappy" Prizm HOB skimmer that does little to nothing for the tank. Amazingly enough, the tank is healthy and has been from its inception in Feb06.

I am in the process of building myself a 20gal sump and need some advice on a skimmer. I have all the equipment other than the skimmer on its way already. The sump will be under the tank in the stand, so I have limited height availability. As I am building the sump myself, I have some control over the space in the tank for the skimmer and though I would like it to be an in-line version, I could live with another HOB if needed. My budget is $425 or less before taxes.

Lastly, I am working on plans for a larger tank...210 to 300gal for the new house that I will be starting to build in the New Year. I would like to have the option to use the new skimmer for that tank but it isn't a firm requirement.

Advice on specific models and where to buy them would be appreciated.

Mark.
