Saw in my local (Shepparton, VIC) Target on Clearance sale an Inspiration Encore Home Gym for $99.83. Seems quite similar to the one in BigW for $299. As it says on the box, only has a 35kg stack of weights, but promises to offer 70kg resistance. No idea of the quality really, but seems to be made by York Fitness, which I thought is at least an ok brand. Not sure if the clearance is in all Target stores, but they said that they have about 30 of them in stock at Shepparton Target.
I think this is the manual of the home gym: http://www.yorkfitness.com.au/uploaded/pdf_28450005Inspirati…
