If you want me to make you feel better I can take a photo of the receipt from my last visit there@NiCd - don't get me looking at the Carbatec site They have recently opened a new store in Hobart, and it will remind me that I need to spend $1k+ on a dust extraction system to go with my new table saw I bought a few months ago :p
It might help :p
How many do you need to buy? I need around 10 if you want to split the cost.I have been able to source a suitable sensor for around $4.80 AUD delivered - I have to buy a few extra but it's not worth my time trying to make up my own at that price. They come complete with a stereo plug on the end so that will save me some time as well.
This is what they will look like
