Check out these deals and you'll see them as low as $169 US on eBay and for $209 at TigerDirect.
Thanks Cp, but my problem there would be shipping/insurance costs to Oz + Customs duties... those would most likely bump the over-all cost to what I'd have to pay locally.
However, I have checked out some local retailers and a few have the Z-5500's for around AUD$300.00, which works out to be about USD$254.00.... so give or take, the prices are roughly equivalent to US prices. One place in Sydney has them for AUD$269.00 (with shipping to Ipswich it would cost me around $290 ish), and another in Brisbane for $279.00... so I'd probably go with those as I could bring them home myself the same day and save 10 bucks... less 3 for train fare.
Yup, they are a definite future investment, but first I gotta get us a washing machine... mrs starkers is tired of taking the washboard down to the creek every day.

Seriously, our current one is 12 years old (they don't build 'em to last any more) and isn't doing a good job any more... not to mention it doesn't stop filling with water these days and has to be attended to prevent overflows.... soap suds all through the house.
Anyhow, thanks again for the heads up... and finding me another way to spend money.
