I'm looking at the Alpine CDA-9831, Alpine CDA-9833, Clarion ProAudio DXZ845MC, Kenwood Excelon KDC-X869, and the Kenwood Excelon KDC-X-879. I'm not sure the differences between these, but they seem to all be similar. I'm choosing these because they are compatible with Sirius, and since I now have three different Sirius radios, I don't want to have two Sirius and one XM. Once you go satellite, you'll never go back ya know......Any help in narrowing this down is greatly appreciated. I have always liked the Alpine, they make a great quality product, but I have also been very pleased with my Clarion head-units and have had no problems with my Kenwood either, so as far as reliability goes they are all equal in my book. Thanks again in advance for any help.
