I've just started new branch of my project, where I try to use **jRails**. As far everything works awesome, except the **autocomplete** (especially `text_field_with_auto_complete`). What would be the best solution to make autocomplete working again?

1. implement whole **autocomplete** by myself (I don't really like this one)
2. rewrite the old prototype helper in jquery and then hack it into **jRails**
3. use some *out of box jquery plugin*
