I have had good share of experience with those Chines and even so called Japanese after market ones and to be frank, they socks! though do the job of physical connection. The cheap glass is the source of problem and to say the least, you will be expert to take out the "Chromatic Aberration" out of your images, in no time... Here are some experience from my past:

I removed the cheap glass (That is needed for infinity focusing) from one of those Chines ones, and like the quality of images are as good as the should be, of course only for the macro or very near field focusing.
Canon has the same macro (No glass) adapters for about 100-200 dollar but why to pay high when you can easily get the same result form after market, much cheaper products.
But the Canon's original FD to EOS converter is a totally different story. Glass on those are excellent Canon quality (No CA or any other imperfection in final image). The problem is that Canon made only a few of them (I believe about 2000 of them only) at the transitional time to switch between older FD / FL mounts to the newer EOS. So they are very very hard to find and even if you do find one, they may be even more expensive that the super telephoto lens itself. You actually can call yourself luck if you find one, but "Unlucky" to pay for!!!
I just don't understand why Canon doesn't make any more effort in bringing a respond to the buyers who like to see this retro conversion. It surely has to do with the marketing of the new products.
If interested check these before the link dies.
