I use a JVC XU-301. As you can see, its a 3 CD, 1 MD recorder/player. Its about as simple as you can get, and it works great.
Just added a new Alpine MDM-7741 on October 17th, 2001. I'm still getting used to having it in my car, but I'm going to be putting a review of it soon on this site and some of the MD discussion places.
