don't have one but I'm with Tim on this one for an economical way and you may consider filling the pvc with that expanding foam spray or even the foam pipe wrap insulation to add some more bouyancy(sp) for added help. Just another Kaizan to the topic. If you use the spray foam then you will have to drill some small holes periodically down the middle to get the spray all the way to the center. Don't use the Triple Expanding stuff because it is pretty potent and could split the pvc the normal expanding should do just fine.
