Every time I go to Petco and Petsmart the (good) heaters are $30+. No wonder so many beginners don't want to shell out that kind of money. That is often more than the tank and lights together!
Before my LFS closed earlier this year
, I found an Elite Mini heater for about $15. I bought it and figured, hey, why not give it a try? Even though it says "preset" on the package, it is adjustable. I like to keep her at a nice toasty 80-82.
So, what items have you had success with but have trouble finding outside of the world of the internet? Please share links here. You might end up really helping someone out!
