Crutchfield.com. They’re more expensive than most, but they’ll give you relatively detailed instructions on how to take the dash panel off, which is the hardest part (although usually you just have to find the right spot and tug, it depends). Also, their customer service is phenomenal, and they have a “Fit Your Car” feature on their website, so they only offer parts that will work for you. You can also search by price and only include decks that have 1/8" male or RCA axillary ports, an iPod connector, or even a USB port.
Basically you have to pop the trim off your car, unscrew the OEM deck, and unhook the harness. Then, depending on what type of harness you buy, you either snap the new one directly from the deck to the car, or solder all the wires from the harness Crutchfield gives you to the harness in the stereo box. It’s all color coded, and I just used heat activated shrink wrap instead of solder. Then attach the bracket (that Crutchfield recommends for you to the new deck, screw it on, and then use the bolts you removed earlier to secure it in place. I’ve done about half a dozen installs, and never had a problem with not securing the back strap they talk about but don’t include. One last thing, since it’s a GM car, you’ll have to use an adapter for the antenna, since GM uses a smaller coaxial than all the other auto manufacturers for some reason.
[del]It sounds like you’d rather not spend more than $100, so here are a few lower end models that seem like what you’re looking for:
Kenwood
Sony
Clarion[/del]
Turns out if you get one of those it’s going to be an extra $45 for install stuff, but you’ll get them all “free” if you spend at least $129 on the deck (basically $10 more for an upgrade, well worth it), so here are my new recommendations:
Kenwood
Blauplunkt London or Blaupunkt San Diego
Clarion
Better Kenwood
Pioneer
This Sony if you wantan iPod connection, this one if you want to use a flashdrive USB with it.
And if you’ll go up to $150, I would highly, highly recommend Alpine . To be honest, I bought my first one ten years ago when I was 16 because of Eazy E’s song “Boys N the Hood”, where he says, “My boy JD was a friend of mine, till I caught him in my car trying to steal my Alpine,” but I’ll tell you what, they’re a remarkable product, IMHO, and offer great features for the money. They run a bit high end, but that model would be the one I would recommend, for sure.
If you have any other questions or clarifications, feel free to PM me if somebody doesn’t drop by the thread to answer it for you and I don’t make it back.
