Personally I found that there was a large improvement over the stock headunit. I like Pioneers, but you'll just have to shop around. The 3-band EQ on my stock 01 PT was decent, while the 2-band EQ on the 02 leaves much to be desired.. Just shop around and find one with a 5+ band EQ with some nice features (you may want to consider USB, satellite radio, etc.). I would personally advise that you use Crutchfield. Their prices are relatively decent, though they won't be the cheapest, but their customer support is well worth the difference. From my experience, they also provide you with all of the necessary items to correctly install whatever you purchase from them, with detailed instructions for your specific car.
