What is your opinion on either of these mechanical aeration schemes.

Simpler is better, at least for me. I have ordered a seat that
will sit on top of a five gallon bucket. You line it with a
plastic garbage bag. Use it, tie the bag shut, and store it
until you find a trash can.

No leaks, no clogs, no thru hulls, no funky odor. Yes, it's a
little gross, but not more so than when the whole system packs it
in and you're reduced to hanging it over the rail.
