Franko--> the one you linked that is on eBay looks pretty good, for the price, the only thing is that the install might be costly. unless you are doing it your self and you are a pro at auto electronics. but you must ask your self, do you want a permanent unit? or one that you can take from one car to another? it all falls on how you'll use it and it's convenience.
BTW is the Pioneer a touch-screen?
