40 gallon breeder is fine. Many go with 4x2x2 for custom builds. That is about 120 gallons I think.
Seconded. I started off with a Zilla brand "kit", which included a 20-gallon tank, lights, and a carpet, but then I upgraded to a 40 gallon breeder after about two months. I'd definitely recommend getting a large tank from the start and buying each piece (lights, furnishings, etc) separately instead of the kit, since the coil UVB lights aren't as effective as the Reptisun 10.0s.
One day I might get around to making him a "crossfire" habitat (
