Cheap Nikon D80 Macro Lens?

I need a cheap macro lens for work.
The lens will be left in the office so it doesn't need to be the most durable.
I was looking into a 50mm then found out that 50mm isn't Macro.
I'm looking for a lens for around $100 - $200 max
Can you please give me some good good focal lengths and cheap brand names?

What's the different effect a 60mm Macro then a 50mm?

Thanks

Added (1). I found a 40mm on this website but doesn't look very appealing.
Its only $190 compared to the $270

Nikon D80 Compatible with this Nikkor 50mm?

I have a Nikon D80 and I need a cheap Macro Lens for product / close up mouth shots.
I was looking into a 50mm seeing as there only $120
I'm trying to make sure the lens will work with the camera body.
I personally use Canon and mine is a 58mm thread but I'm not sure how Nikon tells you.
The 50mm lens is a 52mm thread but I'm not sure how big the thread is in the D80.
Its a work camera that I haven't been able to get my hands on till later today and I need to order the lens this morning.

Here is the lens I'm looking at.

Thank you

Added (1). The ad for the lens says "Note! AF not supported by D40 and D60, D3100, D3000, D5000 cameras" I don't see the D80 in that list so am I okay?
