I have the Jensen TS DVD and it is a very good value for a cheaper unit. It looks and feels like a 2-3yr old Clarion unit. The complaints I have with it are no cool graphics when using it as a radio or CD player, and it does have a tendency to produce slight alternator whine no matter how perfect your ground is. I'm actually considering getting rid of it in the very near future as I've had it for about 3 months and barely use it. it is being used as a supplement for the rest of my system which is all Kenwood 25th Anniversary, except for the subs and rear components which are 12" Alpine Type R DVC running in 1ohm and Alpine 5.25 I-Drive components. If you're looking for something in-expensive with a touch screen the Jensen is a million times better than the dual unit or that Innovatek unit. You can definitely go the used route but be careful buying a screen second hand. Many of these have been abused and are being sold for a reason. If you're looking at touchscreens be especially careful as the oils on our fingers had a tendency to break the older generation screens within a couple of years.
