If you dont want to spend a lot of money, then buy a good unit off Ebay. People are selling those head units all the time. When my CD finally craps, Im going to do that because its already screwing up every once in awhile. You dont really need to upgrade those things unless your really a sound expert. I've played with stereos myself but when I bought my 95 GT for my wife, I was really impressed with the sound, so I'm leaving it alone aside from the jacked up CD player.
