I have a kenwood with the usb input and I like it alot. It has 4 volt preouts, and the usb scans fairly quickly and doesnt have long load times like alot do. It has decent settings and isnt super flashy.
I've had the kenwood USB deck and 3 JVC usb decks and IMO the JVC is way better. Pioneer makes one as well, so does clarion. there are tons out there now. My pick is the JVC kd-g820 or ar880 (been using JVC the last 2 years and they've never let me down)
Pioneer 6000 - I'm sure you can find it for less elsewhere.
I'll be honest, it seems like every thread of yours I read you seem to have done absolutely ZERO research and then when someone suggests a brand you demand them to list all of that brand that fits your criteria. You know it is possible to do something on your own. Searching and researching before you start a new thread can definitely can cut down on the amount of useless posts. Just my $.02 of constructive criticism.
Yea, I wasn't trying to take a shot at you, but just suggesting to throw a little more info into your first post like... "I have been checking out this, this, and this... what do you suggest." I have noticed the same thing in a few of your other threads as well, so just trying to offer a little advice.
