now i need your help: i’ve build a “self-contained” sound board around the raspberry pi 2 to put a software on it that listens and babbles like a child (i.e. not really speech recognition but more like based on speech sounds).

now i want to but the hardware into a nice casing and i checked ebay for a couple of really old transistor radios. here are my top three (in no particular order):

which one should i choose? i really love all three of them, what you do think?
