That's NZ pricing, so that price of NZ$695 is about $400USD.
I assume they're made in China, and therefore assume you can buy similar product from your local Chinesium dealer.
With mine, I had a local shop weld on brackets that let me put them on my FEL, but I matched the standard Kubota pin spacing and used the old school Kubota quick attach. It means I can use them both on the 3ph and the FEl. Not sure it would work as well with SSQA, but in theory you could source and weld on an SSQA plate, and weld it somewhere that it doesn't foul the 3ph pins.
