Was in the same boat as you, so did some poking around the past few days. Just managed to root my Double Power M-975.
First problem was getting ADB drivers installed for the tablet. I found baudi's pdf that did it for me (attached below). Followed that, until the actual rooting at the end. To root, I used SferaDev's Root Rk29 Toolkit (also attached).
Hope this works for you too!
Whew hoo! One thing's for sure, I can always come here to get the best android resources!
