Nano Tank Heaters?

[FishyReef]

The heater on my 10g has started to make a strange popping noise - I'm worried its going to either die on me or get stuck in the on position. I've got an external probe w/ digital thermometer so at least I feel like I can monitor it, but I think I should order a new heater asap. What I really want is the same JBJ titanium heater and probe that I have for my 90, but they don't make one small enough for a 10g nano. Does anyone have recommendations on a decent titanium heater for a nano tank?

Thank you!!

The walmart brand (tetra maybe?) small heater works amazingly, which is rather surprising, but it does
