Thanks for the abuse, simple?
I am not lazy, not trying to get someone else to do it for me and I know where the search box is. I know how frustrating it gets with people looking for the same info all the time on a forum, but never felt the need to have a go and could not find the question.
I did the search and found the list you did and decided that I probably did not want to use a third party device which all seemed to require work that may invalidate warranties should i have issues with the MM system in the future. While I continued to look and price third party devices, in case that was my only solution, I thought that i should ask the question. I really did not see the harm in that. If the answer lies in a thread where i have missed the answer, for that i apologise for breaking your etiquette rules.
Cheers
