It really comes down to how much rice you eat..
Tp4 eats 1500 Calories of Rice each day.. so that's 0.411 kg or 0.9 lbs of rice..
Over a year, that's $330 of Raw rice..
The rice cooker should last at least 5 years..
$330*5 + $269 = $1919 for 5 Years of Rice-perience.
Hmm, I can't argue with your brilliant math.
I'm closer to $79.23*3.14 / 65* 212.43 = $69
If we must be on budget..
look for
Necessary Important Features.
Induction cooking
--- More even heating, Larger heating surface area which include parts of the inner bowl walls
----- vs standard cookers, which only has a heated bottom, and radiates heat upwards
Fuzzy Logic
---- Depending on Air pressure, proximal temperature, rice hydration lvl, water fill lvl, Different heating program is necessary..
Brand
---- Fuzzy logic is a proprietary set of algorithms which comes from extensive testing
--- In that way, relative to the consumer, a long standing company making such cookers w/ a degree of (rice pedigree) has the best algorithms..
