800w titanium heater

I have been trying to purchase one of your 800w titanium heater tubes. Everyone that had carrier them advised they were recalled and that a new version should be available some time in the future. Do you have any idea when these new heaters will be available for purchase. I am running my 300 gal reef system on a backup heater and need a new heater soon. I can wait a week or two, but not several months.
