It might be possible to build one for under $15 but I'm not sure how it
might be affected by being handheld while searching for a transmitter.

The RF receiver modules that I specified the BX24-AHT and roZetta have a
linear output pin which can be used as a signal strength indicator. You
would want an inefficient antenna, a battery and you might get buy with a
multimeter as the readout. More likely you would need a PIC and an LED or
some type of visual indicator.
