I got my first automatic over Christmas (the super cheap seiko - I want to decide if I like the automatics on an entry level before splurging)... the only other post i see here about winders seems to suggest letting them just wind down when not in use. I've had trouble accurately setting the day/date (it skips a day ahead at noon, goes to spanish, etc) and thought a winder would solve it.

Two questions:

1 - do you use a winder? why or why not?
2 - would one of the $40ish models on amazon get the job done (vs. something fancy $150+)?
