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.
These are my opinions, not necessarily my employer's. I hate spam.
