I have some of the same reservations. I do not doubt my abilities to design and build a great set of stabilizers however, being a former Crew Chief, helicopter mechanic and Co-Pilot/AeroScout, I have a tendency to err toward the safest and best designed solution. That would have cost me way more than anyone of these:

Since stability while in motion is not an issue for me and most of my fishing is done while anchored I bought the Ethafoam floats. I can always switch them for the hydrodynamic floats later on if I wish to. It only took about three days for me to receive my order, if I recall correctly.
I will be installing them tomorrow for the first time. I will update you all on how well they work and hope to get some pictures too.
Meanwhile, turn on your audio and enjoy their youtube demo here:

For some folks, like me, buying a second or different watercraft is just not possible. May not be practical either.
