Vintage cabinet with newer chassis?

howdy,i'm new to the site and i like vintage televisions and radios and what not..i'm pretty much crazy for anything from the 40s or 50s..i'd like to put an older set in my living room,but because of budget constraints and availability and price issues, i'm probably going to find either an already empty cabinet and stick a new tv in it, or get a junker that's beyond repair and do the same.either way,i want to completely hide the new set inside the older cabinet and make it look somewhat stock.some questions i have are : anyone know of a place in or near columbus ohio where i can find a vintage set for cheap/free? and also if anyone knows of a site that could give some tips and hints on doing this. i know this might anger a ton of people, but i'm just askin for a little help.thanks in advance to anyone who can help!
