They have a good price on unbreakable heaters, but it looks like it isn't a name brand. Item #MA-11958. When I called they told me it was made by a company called Commodity Axis, that they never had one returned and that it comes with a 6 month warantee? I'd like an unbreakable heater since I have some boisterous fish, and the external control looks good. I also have my eye on some from e-bay and Big Al's (though someone posting having trouble with returns at Big Al's has me worried)
