I had a LectraSan - I still have it with a brand new motherboard which I will put up for sale at some point. Tearing this apart totally sucks - there are a dozen screws that hold the top housing together and frankly, is worse than a holding tank for service.
1. If you are not in Salt Water, you will need some sort of salt feeding system. The slightly brackish waters of San Francisco Bay - the middle of the Bay - was likely the cause of some of my problems
2. It still has something resembling a macerator which is not only a failure point, but could get bound-up by a user who flushes a wipe or worse
3. Parts are expensive - the motherboard is something close to $700 as I recall. The electrode pack is not exactly reliable either. The price of these two parts is more than a new unit, so it's an expensive system if anything goes wrong, which it did for me twice in the 5-or so years I had it installed.
4. If you think it's legal to pump from LS into a holding tank in an NDZ, then overboard within the 3-mile limit, think again. Once the effluent goes into the holding tank, it loses its legally protected status for overboard discharge.
All I can tell you is that for me, the LectraScan (whatever its called these days) was part of the problem, not the solution. I did not find it to be reliable, and a PITA to service.
