I have a Husqvarna 128LD and am using string but am tempted to get one of those fancy replacement heads. Anybody ditch the string and get those fancy heads with the gizmos? Can anybody recommend one?

it depends on what you are whacking.
seriously, if you weed whack along a lot of hardscape (stone or concrete walls, for example), or you use the weed whacker as a makeshift edger, then you should use a head system that can auto-feed line with a tap. but if you are just cutting grass without danger of striking stone or concrete, then a gizmo head may work.
ps you can also get a single strand head. it accepts a ~1 foot long piece of standard string. you use it until it's worn, pull it out, put a new piece in. you can even purchase the string in pre-cut lengths. take a bundle with you and head out with the weed whacker.
