I like the Sony'* myself. Cheap, lot'* of features, decent sound. I ain't gonna win any rolling thunder contests, but I can drown out the crappy music from the car next door, and stay within my budget (plus, they're the only one I trust that have red lights)
Here'* the one I just got (after the break in) $119 at Circuit City
Dual makes decent, really cheap systems. Ran one of them for quite a while, before I got aggravated at the lack of a cloak.
1998 SE Midnight Blue Pearl
Gutted airbox, FRAM AirHog, removed MAF Screen, eBay clear corners, extended brake lights
I'm so much cooler online
