I think I got mine for like $800 a few years ago. I Expect that price to increase to somewhere around price of this listing if/when they get re-released by JJP. Took me a week of evenings after work to install - maybe 12 hours total? Was a great learning experience. Directions are logical, detailed and easy to follow. Agree that these are a must have if you love your original WoZ. GLWS!
