Power handles for swimbait reels?

[fishindds]

I am a novice at throwing swimbaits but have noticed several knowledgeable fishing guides recommend this addition to their set up.I have several Calcutta reels and would like modify one or two for swimbait use. What is the best resource to buy these. Is there a better/best outfit to purchase from?
Thanks for any assistance you all can provide!

I had Dave's Reel Service outside of Chicago put a power handle on a Calcutta D 401 and I absolutely love it. The problem is I'm still rehabbing my second full shoulder replacement and my surgeon does not think it's prudent for me to go back to throwing large swimbaits so it needs a new home. I'll let it go for a reasonable price if you are interested. The power handle modification was around $75. I also left you a PM.
