I've been a Bell user for several models.   Its a solid product.  Those V-1 folks are crazy loyal to their detectors and swear by them.  My boss has one.  We go to lunch daily.  I'm not all that impressed.  I am, however, impressed with the fact they can be upgraded so you don't have to buy another detector.  But that's squashed by the lack of cool-factor features that the Bell has..
$290 is still to high. 
Overstock.com has it cheaper and so do 
these goons.  I've shopped overstock.com before.  They rock.
