I highly recommend bergvill fx stereo kits! They use continental head units that have a near-exact match for nighttime color to the factory interior illumination. The look is also pretty period correct, IMO. I installed one after my stereo started acting up, and I haven't been disappointed. Just be sure you get the correct wiring harness adapter. It's a true plug and play install.

Here's the result of my install:
It looks OEM enough for me and has the nice modern features all for a very reasonable price.
There's also a very pricey but nice Porsche solution:
