Aftermarket Radio Opinions Wanted

Thinking about upgrading my thumbwheel radio to a modern lookalike with bluetooth etc and am looking for opinions. Whats peoples experience with retro radios such as Redondo or others? Qualilty/fit/finish?
You could leave the stock radio alone, and use your smartphone to stream music into a Digital Signal Processor with a built in amp via bluetooth and then on to your speakers which can be concealed or not.
