I bought the kenko ones, there is no optical element so just about any make will do.
I just posted an image I took with a Canon 100 f2.8 macro + 25mm ext tube +2x converter. - See my latest blog entry below if you are interested.

I have some of the kenko ones as well - they are great for cheaply macro-izing any lens you have.
I also have a set of macro-filters (lenses) that do the same. Advantage of the tubes is that they'll work with any lens, filters have a certain size they fit on. Disadvantage is that tubes slow down a lens - you need more light, while the filters don't. Advantage for tubes is that there are no additional optics, unlike the extra lens of the macro-filter.
I think it's worth getting a cheap one or a set to let you work in close just in case you need to. |

Geez, what's that magnification ratio again... 1:1 + 2x should be 2:1 and then 25mm should make it just a tad more? 2.125:1 ?
