You can say all you like about pumps but I've always thought stretchers made more sense.
I'd probably blow my rainy day fund for a good stretcher.
Not the un-circumcision kits with the big scary weights, the little spring loaded ones... Or that one vacuum/rope-stretchy one.

Also, I always thought that it would be cool if we could have, like... A stock marquee or something like that, with products and their stats so far as ratings, or how popular they are as far as sales.
