There are some pretty nice looking models here...........check out the Spitfire.

Also several other in the same area, including some Mustangs..

These models are of a very high quality , one shop in Albury/Woodonga had a huge selection and wicked prices to match , but the B24,17 and Lanc 1/48 scale were simply perfect! almost worth a trip over there to buy one .

Look pretty nice and not to expensive for the spitty.
They look really well made.

Not diecast but I bought some pretty cool snap together 1:200 models off of TradeMe a couple of weeks ago.
They were pretty cheap ($40 for two including courier) and I got two, an Air NZ 737 and a Freedom Air 737.
Here's the linkto his TradeMe listings if anyone's interested

Also the diecasts Bazza linked to look very nice and not a bad price.
