Alon, this I know... I'm trying to avoid the PalmPilots.
But aren't there individual units that simply plug into your car (and it tells you the data through it's own... err, 'unit')? I think those might be more costly though.
I checked out Ease, but the cheapest one they had was $600! Unless I didn't check thoroughly enough.
Any other suggested products?
