Electric is the way to go. I use the fine cutting plate and put it through twice.
Somecutting platescan rust so store them in oil.
$75 - $100 for a good one, andan aluminum head will save some money overstainless steel. Circuit City online has a Panasonic modelthat's highly rated with free shipping for about $95.
