HAHAHAHA! I was thinking the same exact thing but didn't want to be "That Guy"!
I've never seen a transducer in action, so it'll be interesting.
LOL - Couldn't help myself - but for $20 it's not gonna break the bank and I agree it will be interesting to hear about the results
Have you tried pawn shops?
Good idea - I'll check them if Goodwill doesn't have anything.
EDIT : Checked Goodwill today and they had some tvs for $10 that would have worked fine but while looking through the AC adapter box came across an old Radio Shack RF Modulator that had the Audio video in that the unit needed and then coaxial output to the TV using channel 3 or 4 on the tuner for $2
( So can use this with the disney TV and not have to deal with switching modes every time it is turned on as it will come on to channel 4 just fine from powered off so now can make it work with just the 1 button press like wanted - though it uses about 4.5W of extra power to run the modulator.)
