I've been looking for a distance sensor capable of around 20ft that is rated for outdoor use, and looking at the cost of these it seems they are way overpriced, does anyone know why they are so expensive besides being slapped inside of a PVC enclosure?  Would it be feasible to make your own much cheaper, or am I missing some kind of magic besides being in an enclosure protected from the elements?

Here is one of the nicer ones I found, but I need a few of these and $80+ seems excessive...

It's probably expensive because the thing is high accuracy and weatherproof.
Maybe you could hack one of these or even consider something like this to hack.
Don't PM me for help as I will ignore it.
