Great advice everyone, thanks for your time and effort.
Wilson,
I have a Seaclone 100 HOB skimmer on my 20 gallon long that I got a great price on. It does a fantastic job for me. I have only two fish in my tank as there isn't a whole lot of swim room with the live rock. They are small, both damsels, and so I won't have an overstocking issue.
You can get good pricing and reasonable shipping at

It will give you enough capacity to move up to 55 gallon tank in the future.
