yup, I second H3D's vote for the Stealth by Visi-Therm. I did not know they were a Marineland product, so voted Other. The other Marineland heaters I've tried are OK, but not as good as the Visi-Therm line. So maybe my vote in Other was appropriate
The Stealths are nice, but I am holding out judgement on them until they have been in use for at least 5+ yeats. The Ebos are great all-round, and I have some that have been running reliably for well over 1½ decades.
