I'm running the OME setup, and it made my street driving WAY better. Much softer ride on and off road. I run on street, fire roads, mildly difficult trails, snow, jump it in the sand... It's WELL worth the money. Only 1.5" of lift, but... if you really want 3", you can slap on a body lift (I don't like 'em, but they're cheap) or small spacer lift.
Once you drive OME, you won't want anything else. And, you can find them new for $700 - used for 1/3 that if you watch ebay & the message boards.
