Marketplace
Not as good as this previous deal (http://www.ozbargain.com.au/node/88916) but still not bad for someone in the market for a decent GPS. They seem to have reduced the price by $30 since yesterday (24/Jan) when I posted this initially (it was for $149).
If you're prepared to spend $149, then I'd suggest the nüvi 2455LMT for $147 from The Good Guys if not a better deal, at least worthy of consideration, unless you wanted a 5-inch screen:

With the comparison, I could only find the 1450T, not 1450LMT, so just add back the lifetime maps bit.
