dual is certainly better than pyle (afaik the latter is about as low as you go, even among flea market brands), but still crap. just pay the money for a pioneer. they generally seem to have the best price/performance. among the other brands, i generally find kenwood pretty inferior and aiwa pretty overpriced. sony is flea market crap at three times the cost. not even sure what else is popular anymore.
so yeah, save and buy a pioneer so you don't have to buy a new one next year.
