Hi Exfso
Yes, it actually does work. I have the Multi Purpose Coma Corrector by Baader. I was not able to source it here in Australia. I eventually got it from Alpine Astronomical. Pricing is on the site ($US).

There was some speculation that the MPCC would overcorrect on the SN scopes. One guy from the States has done some ray tracing on the combo. He says that there is very slight over correction in the centre of the image and there are also slight problem with chromatic aberation. Also, if I can trim my T-mount adapter by 4 mm, I am told that it will perform even better (I'm not about to do that btw). All I can say is that my images are much better with the MPCC than without it. Check out my other thread on the tarantula (Gee I'm Bored). They were taken with the MPCC.
Cheers
