I got the Rapala Cordless (Lithium) and the thing is the best since fileted crappie (yeah, it's better than sliced bread). No looking for power and the battery has gone through 100's of crappie on a single charge.
Found a couple American Anglers in a box in the shop cleaning stuff out for a garage sale a couple months ago! It was like Christmas. They're the best I've used. Mister twisters last about six months and the Rapalas usually haven't gotten through a cooler of fish before they [censored] out.
