A good heater for a 2g pico?

[Northwest_Scapes_]

So I'm really interested in setting up a 2 gallon pico, mainly with just GSP and some sort of encruster like leptoseris. Does anyone have a good heater recommendation? The one I've seen a lot of people use has been discontinued it seems like so im looking for something new

Cobalt neo therm mini is great but you'll want a temp controller with it
