The problem with an auto-focus lens and an extension tube for me is that the auto-focus lens, because of the small motor etc., only has about 90deg travel around the circumference of the lens, and so fine focus is sometimes hard. Just taking your fingers away after focusing can be enough to knock the focus ring enough to throw focus off. The Auto Macro lenses have a longer focus travel (at least one full turn I think) so that helps.
Still I find I can compose the depth of field better if I can control the focus.
I would like a 25mm ext tube though to use with my 50 and 18-55 and will probably go down that path until I can afford the 70/90/100mm macro lens (must stop buying telescopes and buy camera lenses for a while).
A tip for macro shooting which you may already know, so please excuse me, but if not; I spend a lot of time with my camera on the ground to shoot fungi and have emptied a bag of rice into a ziploc bag (and bagged that in a second for security).
The camera sits stable on it and can be positioned for composition. Thanks to the lovely reticulated view finder screen on the eos600 (and it's 5&10x mag it makes shooting easy.

Ive found that the 600D is not real quick on AF with moving bugs, (not greatest for sports either) & not sure how much better a top-line camera would bee, Trevor

The kenko's have all the contacts for the lenses, so everthing works as well as if without them (y)
Thought the rice was going to bee for attracting certain critters, maybe a few chinese tourists
Great Idea by the sound and if one ever gets peckish (y)
The swivel view panel on the 600D is worth its weight in gold

Thanx Edison, no lighting applications etc, just natural.
Exposure for Bee was 1/1250th F6.3 iso400 - I had no idea the wings would be frozen - now I do
