Spectra is now owned by Katadyn. Consider contacting their support (support is excellent, in my experience) and asking if parts will be available for both models for the foreseeable future.

I have the larger sized Katadyn PowerSurvivor (160gpd). It's been a good unit, very simple and easy to take care of. The automation on the Spectras is definitely convenient, though, especially automatic back-flushing so you don't have to do it yourself or pickle the watermaker.

The 6-7 gph watermaker works well in my use, where it's mostly one or two people on the boat and I'm underway for 4+ hours most days. Since these are both DC units, it's ideal to run them when underway when there's plenty of power, cleaner water, and other machinery noises to mask the watermaker noise.

If I was the type to spend an hour or two underway then a week at anchor, I think I'd go with a big AC watermaker to crank out a bunch of gallons with the least amount of generator time...
