i just want a $1k-$2k 'toaster oven' that can do 8"x8" (give or take) that has no spots that get 10C hotter than others.
im looking at the Elektor oven https://www.elektor.com/projects/smt-ov ... 80/smtoven
but US is 120V and this is 220V and usually thats hard to fix with a heating element.
220/240 is available everywhere in the US- even NYC :)
All banned (and a lot of office) power is delivered on two 110 volt legs each 180 degrees out of phase with the other. Either phase to ground gives you 110v. Connecting across one phase to the other gives you 220v. In your electrical box- every other breaker on a side is connected to the same leg. So on the left side- breakers 1,3,5, and 7 are connected to the first leg, and breakers 2,4,6 and 8 are connected to the other leg. The same is true for the right side. To get 220v you use a double wide breaker that connects to both legs. You could easily make this change yourself but it's probably not legal in a commercial space. An electrician could give you a 220v/240v outlet in a few minutes.
Whether you have 208v or 240v depends on how the power is brought in. In some larger buildings power is brought in as 3 phase and you get two legs. Unfortunately the two legs aren't 180 degrees out of phase (they're 120 degrees out) so you end up with 208v (sin 120 * 240) instead of 240v. Either way it generally works just fine.
