Spax Front Adjustable Shocks

Hi Guys,
What are people's opinions in these shocks?
I had a pair about 10 years ago and they seemed ok but am now upgrading the current escort and what to know how they compare to Koni's.
As Koni's are hard to grsb I thought these may be another option.
At $425 a pair from http://www.rsparts.com.au/ I thought they maybe an option.
Cheers,
Matt
