i've dealt with ergo audio in the past and considered them first when planning a system to replace the pathetic delphi unit that came in my sierra. they offered me an alpine 7998 and AInet XM tuner for $849. not sure if this includes the antenna or installing my alpine V12 5 channel (since the 7998 is preamp only) but the lowest i could find a 7998 for was $530 on eBay, figure another $25-$30 shipping. i was quoted $599 for the unit alone, this sounds good considering i won't have to pay shipping or install it. advice appreciated!
