Games masters have them here in Australia $535 
good investment imo
I've seen some really poor quality local copies - so if this style of lift is preferable, stick with the Gamemasters version.
This one here is best value for money in my opinion https://www.machineryhouse.com.au/J048
Had it for 5 years with no problems, don't get the next model up as it can be too wide to fit between legs of some older machines
These are the ones we use.
