There is another thread about this as well posted the other day:

Basically the argument is going to come down to the Valentine One or the Escort 9500ix. The Valentine offers the arrows and bogey counter which some people absolutely love, while the 9500ix offers GPS features that lockout constant falses on roads you normally travel.
I have the 9500ix and absolutely love it. I looked at the V1, but the visual design is not appealing.
