I'm with vetspet -
I work at a camp and see all the electrics in use - some are better than others, mostly in ergonomics, but definately not worth the extra $$$.
I cleaned over 1000 fish last summer (pike/walleye) and went through four wal-mart $9 electric knives. When they stop working, save the blades and throw the rest out. Although they may not look pretty, they work just as good as the high priced ones.
In my opinion, based on what I used and observed, save your money and buy the cheap ones.
