The Kenko DG AF set are good and are quite a lot cheaper than the Canon set.
You have to make sure you get the AF set then all the automatic bits on the lens will eork such as autofocus.
But you will almost certainly need a tripod because the DOF is extremely small.
EDIT: they sometimes come up on here for sale so keep a look out in the "for sale" section and save money.

These are the Kenko tubes Peter mentions http://www.warehouseexpress.com/buy-kenko-dg-canon-af-extension-tubes-set-36mm-20mm-12mm-/p1005553
They work great - lots of folks use them. You can get them cheaper if you search around. I bought a used set off here for £80.

tnx guys.
Do the extension tubes magnify more the subject? Im trying to shoot with the 100 2.8 and setting it at 1.1 I simply have to go back and forth infront of the subject until it comes in focus? I was expecting a bit more sophistication
Also just took me a little insect about 2 mil. It certainly didnt fill no screen. Is macro, shoot now crop later to desired size? Will extensions do the job as a macro lens alone is not enough?
Tnx Ramon

Extension tubes will give greater manification when attached to the 100mm Macro.
You will definitely need a sturdy tripod and most people using extension tubes on a Macro end up buying a special rack for the camera to mount on.
This allows fine adjustment.
You must also realise that even with a 2: magnification factor a 2mm insect will still only be 4mm on your sensor.
So if you want a large pic you still have to crop and enlarge.
Learning to take good macros involves quite a large learning curve.

You've such a small DOF with macro rocking is definately the way to focus
with a macro lens 1:1 means a object the same size of the sensor in you camera will fill you frame - so if you use a Nikon crop format camera a object approx 23mm long will fill the frame
or half size at 1:2 46mm
with tubes you will get 2:1 twice life size this will show you about 12mm with the ruler test - i dont have a image to post and i am FF now so i cant take one. :bonk:

Extension tubes allow you to focus closer, and that increases magnification. Most people use manual focus, rocking gently back and forth, and a ring-flash helps enormously to get a good amount of quality light on the subject, without camera shake.
If you want to go higher than 1:1 magnification, that gets extremely challenging. Canon make a lens specifically for this, the MP-E 65mm which goes to 5:1 (subject 2mm long appears 10mm long on the sensor) but it is very hard to use well.
Just a thought, a teleconverter gives a bit more magnification by increasing focal length, without reducing the focusing distance. I have used a 1.4x Kenko Pro 300 with a Canon 100 macro and that worked well, but it only increases magnification to 1.4x (before adding tubes).
