You will be very mistaken about the quality and price of the D40. Today, I bought a D40.. not for myself though.
940 with 5% GST is going to bring you to about 980.00. NIkon's cost to the shops is about 940.00-960.00. You must not forget the other costings like importing cost and other cost.
I would think that for 980.00-1080.00 its a good price. Before you make a comparison with the D50.. I would suggest you go and feel the D40.
Its a really amazing camera, for its size. It comes with a free 1GB Sandisk standard SD-Card.
So all in all I think its a great price. its about 250.00 dollars more expensive then some of the 7MP P&S.
Cathay's price was 1080.00, I am sure that if you have some good relationship with them, the price can go down to who knows how much.
Also.. lets say with 12month interest-free credit, that about 80.00 per month.
Why get a second hand camera, when you can get a brand new camera.
Normally their list price is normally mark up by at least 30% minimum...
You must ALWAYS bargain as their profit margin is very very high...
