What do you guys think about this (Alba Electronic Noise Squeak Rattle Detector)?

Anyone ever used something similar? I have some rattles in the car and it's sometimes very hard to identify where they're coming from.

It's fairly expensive, so I was wondering if people would be interesting in "sharing" one? For example, I could buy this, and then people could pay me like $15-20 + shipping to borrow it for like a week or whatever (you would pay me like a $100 guarantee and I'd refund you $80-85 when you send it back). If we get people interested back-to-back you don't even have to pay for shipping it back, you'd just ship it to the next guy. Whatcha guys think? If there are enough people interested, I'll buy it. I know i'd pay $20 to have something like this for a week lol
