I've had cameras ( and recorders ) for at least 15 years , with at least a couple of small 19" Tvs on all the time , and also picture in picture when the TVs are on .
Not a direct answer , but I assume that is what most people do these days ? More discrete , better picture , with record function .
As far as I can work out , a camera on its own is under $50 , a 19" flat screen TV probably $20 second hand ( lets face it , no-one wants them these days , and the older Analogue ones still work as a monitor ) .
I'm in NZ , I googled and this one came up as being stainless and is $25 ( well $23.95 )
-- it is a smaller importer . Bunnings etc does seem to have brass only .
