Lectra/San not that hard to install
And requires far LESS maintenance than the AirHead--in fact, none except an occasional cleaning, which doesn't require taking it apart but only pouring a solution of muriatic acid and water down the toilet according to directions. And it can be used with any toilet, manual or electric.No paper bowl liners to deal with or gallon jugs of urine to store aboard and then take ashore or pour over the side at sea (but only outside the "3 mile limit"). Nothing to empty at all, nor any chemicals or biological "starters"...just flush the toilet and push a button.Quite few people here have installed Lectra/Sans...and they all love 'em. You would too.But it's your boat and your choice.
