i can't really understand why you desire this.
but then...no one can truly understand the desire of another.
i do know that sometimes it is worthy to really think about want versus need, or in this case, why you are not satisfied with what you have. what you have is a selection of tools that perform beautifully, meet your needs and are paid for in full, both cash wise and in an environmental cost sense.
so....buying a new, mid to high level machine seems to me to be about something other than the tool. maybe you want to know what that is, maybe you don't. only you can say.
