Went to Autogeek.net after reading up on the positive reviews of this unit in the maintainence (wash and wax) thread... Then I searched for coupons @ couponchief.com...

the code AGO in the discount field scored me free shipping and saved me 22 bucks, plus the starter kit has 4 pads included that you choose! I priced the unit alone on Amazon, and even with free shipping, the pads are 11-12 bucks apiece! Ended up paying 179.00 for complete kit... very pleased!
