Replacement radio for 1973 Eldo

I have a '73 Eldo convertible and the Wonderbar radio is dead after fading away for years. I've seen rebuilds for many hundreds of dollars, but I'm not THAT interested. But I also don't want a Walmart cheapo unit sticking under the dash. Does anyone know of an am/fm unit that looks sort of like the original and will fit in the space in the dash? I used to have a weblink to a company that does this but it doesn't work anymore.
