Thanks Mark, looking out for this baby.
....you can get a very similar one in Aus. at Bunnings Hardware stores for about $15, they're used by boat builders to mix up the fibreglass 'slurry' they use for hull repairs. I use one on a large drill for my 10-20L size buckets and its a very efficient brute!
Thanks Irene, wll check it out when next on the mainland
