The rechargeables get heavy pretty quick. Also, the batteries are only designed to last about 2 yrs. Once the battery goes out, it's dead. Several models that I tried were 'battery only' meaning that you had to have the battery charged before using it. Can't just plug it in and keep going when the battery gets weak.
I went through 5 or 6 Mister Twisters after they switched to the 'heavy duty motor'. Seems that as part of that switch, they also switched to plastic gears. They warranteed them out but it was a pain to keep shipping them back and forth. They may work fine on smaller bass and crappie but those striper rib bones will tear those gears out.
I got a good AC/DC one and I think that it was an American Angler or something like that. It's in the RV and I can't check the exact brand.
I have an old Hamilton/Scovill that just keeps going. Sharpened the blades until they wouldn't sharpen any more and now I'm on my second set of blades.
Check out some of the Alaska fishing websites for recs. Those guys put a knife to the test.
