I have a Shimano Tranx 200, tackle direct has them, unfortunately I can not give a review on it because i just got it, but I paired it to a Dark Matter rod.
All my reels have power handles, with the advent of 6,7,8 to 1 ratios , they are a necessity, amazon has them for as little as 12$ and they are well worth it.
Here is the link for the handles, it took a week to get them, but well worth the wait.
They fit Shimano, Diawa,Quantum you name it.
