The RetroSound stereos are really nice...especially with all of the options you have for the face and knobs. The above mentioned Philips is pretty cool in its own right too but I don't really see it as retro...looks more fitting in a modern car with a minimalistic interior.
Here's what I'm planning for my own SPi:
I originally wanted a RetroSound but since our Minis have a bit more of a modern interior/dash, I think it would be cool and aesthetically better to go with a period correct stereo.
I researched quality late 80's/early 90's head units. I really like the look of the older Alpines and just purchased an Alpine 7619r. The 7618/7619r were Alpine's flagship models in the early 90's.
A nice writeup about the 7618r here: http://retrorides.pr...m/thread/144959
I picked the 7619r as it has modern day features that were very high-tech when new...like RDS.
Like you, I spend most of my time listening to music I carry on my iPhone so I want to be able to connect it to my head-unit. Older higher-end Alpine's like this have an M-Bus connection in the back so you can connect the stereo to a CD changer that you keep elsewhere in the car but control from the head-unit.
3rd party companies offer modern adapters that connect to the M-Bus and allow you to plug in USB drives or AUX cables to have direct audio-in. Just search 'Alpine M-Bus' on eBay or Amazon.
The best one I've seen is from a company called "Yatour". They make an M-Bus media adapter with an optional bluetooth kit that gives you the ability to stream your music, has handsfree capabilities and automatically connects to your phone once you've paired it once.

I think they have a new bluetooth module for 2015 so you won't need both the adapter and BT kit...that should save some money and clean up wiring behind the dash.
Anyway, this is my plan for the SPi. Looks like a period clean (non flashy) cassette stereo to the casual eye but is a very HQ system adapted with bluetooth for music & handsfree calling.
