I'm looking for reccomendations for teleconverters (1.4x) for use with Canon EF mount lenses. Now, I know that some have protruding elements that limit their use to certain lenses, but I'm looking for a decent one without protruding elements that should work with most/all EF lenses.
As of right now, I'm using a Sigma 70-300 4.0-5.6 Macro APO Super II, and would like a little more length for bright light motorsports photography.
Any reccomendations?

Neither Canon nor Sigma will work with your lens, they only work with telephotos L series (canon) and EX series (sigma).
I have the tamron 1.4x, it works good with any kind and type of lenses.

I had a hunch... my Canon/Sigma comment in my subject line was actually related more to the lens types and not teleconverter brands...
I've seen 1.4x TCs from Tamron and Kenko... how do you like your Tamron? Any issues with it? Comments?

I have the Tamron 1.4x (the cheaper version, not the "pro" version) and it is decent glass. I remember a few months ago someone over at DPReview posted a comparison between the Tamron and a Canon. The Canon was better, but the difference was subtle, and there's the compatibility issue, and the fact that the Canon is 4x the price of the Tamron.
Bottom line, if you need to worry about compatibility (you have non-L and/or non-Canon lenses that you want to use it with) the lower-priced Tamron is a good choice. Be aware that there may be some compatibility issues with non-Canon converters as well, so make sure the particular converter you are looking at is compatible with the lenses you want to use it with.
A final note: many of the non-Canon converters do not tell the camera that they are there, therefore your focal length information in EXIF will be incorrect. The lens/converter combination will also report the wrong aperture (since the 1.4x converters lose a stop). A side benefit of this is that you may retain some AF in good light at f/8 with the non 1-series bodies. Good news if you are using it with a lens with a max aperture of f/5.6, which isn't at all uncommon.
