I have all but the home made, unless you count some of the mods I have done on commercial filters. In that case I have all of the listed types. You left out the box filter that I run and the UGFs that I once had on all of my tanks.
30 gal - Eheim 2215 external. Came with free with the tank when I bought it at a car boot sale for £22 . So I got 70 odd quids worth of fully functional filter for nowt
