If you want something "name brand"...check out kenwood. They have a touch screen comparable to the pioneer....BUT, good luck getting it to work with a CPU, it will take a lot of work. I had the old 5.5 inch kenwood touch screen...never could get it to work. Pioneer 7300 is TAF though...not touch screen, but very nice.
I'm a ghost...email me if you have any questions on my old setup
