Powerhead for 14g Biocube?

[johnnalei]

So I want to add a powerhead to my 14 gallon biocube, but don't know how to find a nice compact one. I picked one up from the store that looked small to me, but then in the tank it just took up too much room. I've seen pics of people w/biocubes or similar tanks that have unobtrusive powerheads set up, so I know they exist. Any suggestions on brand/model that would work well? Thanks!
