Just to correct this a Janson MB-300 is the cheapest new that I have found in the UK. Just that they can not get into tight spaces, if I had a field to trench yes the cheapest option.
Wendelspanswick, thanks for the links, but waaaaaaaaaaay to big for back garden, but you have given me a new name to search on though, apart from buying a cheap one for the parts at some time, I think the rams would still be to big, so I will see if they do these for the mini tractors.
But looks like my main question has been answered, yes others have/are thinking about it one is doing something about it.
