alpine and eclipse are ur best bet.
personally eclipse
1 u cant beat there warranty
2 the sound quality is great
3 the ability to tune your system with the upper end decks are great for the money
4 5 volt bench pre out on decks 54 and up

the only jvc deck i simi like is the digi. other than that i never liked them
motorized kenwood decks from my past experience always break
and sony, just dont buy it
