I've had four URL's recommended in this thread so far. A status report...
1. Live.Aquariu.com -- does not exist. If there is a typo, I am not sure what the correct URL is supposed to be here.
2. LiveAqauri.com -- does not exist. Tried "LiveAquari.com", that just gives a list of other sponsored links., as does LiveAquarium.com.
3. Etropicals.com -- great site, but they don't list heaters anywhere.
4. Bigals.com -- does not exist. Sure it should be "Bigalsonline.com." The only titaniums they sell are the Via-Aqua ones, which some seem to have problems with.
So while I appreciate all the help in trying to find a good source for these online, so far the help hasn't been entirely that helpful.
