A Z3801A runs off 48V. Some are 24V. I doubt if you will find one for $200.
EBay has one for $500 and another for $1000.
A Trimble Thunderbolt needs +12, +5, and +12. EBay has one for $110 and 2
more for $250.
In both cases, round up for an antenna.

Neither the Z3801A nor the TBolt are setup to power the oven while the reset
of the setup is powered down.
