Thanks for the replies.
I'm in Mudgee NSW Brett, thanks for the offer, bit far.
In my head, I know KK is probably right and I may keep an eye out for a used opportunity, even if just for peace of mind, try for myself.
However, I took up an offering of new Sette 270WI at a good price. I figure it will do for the next couple months and then serve as a reasonable back up.
I also decided to get Niche Zero which will be at least a couple months away. Although it's not yet proven, everything about it suits, single-dose, 63mm conical burrs, easy fit in space, no retention, etc... Just hoping it performs, time will tell, early indications have been positive.
