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.
