What is a affordable and good macro lens for my nikon D3100?

The only AF-S Nikkor lens that is "affordable" is the 60 mm f/2.8. $600 or 85 mm f/3.5, $530

When people ask for "affordable" lenses, we really need some kind of budget to answer.

My last lens cost me just over $6000 and it was a bargain for what it does.

Tamron 90mm f2.8 or Sigma 105mm f2.8

Both great lenses.

Here are a few to look at:

Tamron 90mm f2.8 SP AF, $409.95 after a $50.00 mail-in rebate. No auto focus on your D3100.

Sigma 50mm f2.8 EX DG AF, $299.00. No auto focus on your D3100.

Sigma 105mm f2.8 EX DG, $479.00. No auto focus on your D3100.

Tokina 100mm f2.8 AT-X M100 Pro D AF, $399.00. No auto focus on your D3100.

Most macro photography is done using manual focus.

Nikon 50/1, 8D and extension tubes

Try Sigma 70-300mm f/4-5.6
I purchased this lens for my Nikon D3100, and absolutely love it! My picture quality is great, way better than using my 18-55mm lens that came with the camera. I highly recommend this lens to users who are just getting into photography, and are looking for some bigger lenses! Definitely worth the money!
