I bought an Eclipse CD1200G but I decided that I wanna go with a headunit-less setup instead.

It's only been in the car for about a week, and it's an awesome unit. It will need a double din kit like the DDMWorks or something equivalent, otherwise there will be a gap on the top and bottom. They charge $60 to custom fit a dash kit for your Miata. Here's the radio itself:

I paid $100 but I'll take $85 picked up. This is an awesome looking headunit that gives a factory look while giving all the modern features with iPod, USB, aux, MP3, WMA, AAC and etc.
