Been on sky for over a year, had line issues recently and sky were great in sorting it out.

However, i want to be able to use a tool i used to use pre sky, DMT tool.
I am using the 934 however.

Can i buy a 834GT off ebay and then be able to use v8 of the DMT tool?

I do have a speedtouch 585 here, but i would rather not upset sky, they are a good service, to me at least anyway.

Many thanks for your help,
