RV Parts Market has the Smart Light 1000 for $44.77. I don't know anything about this company, nor the shipping amount.
I thought the price was pretty low, so I double checked to make sure the Revolution bulb was included, which it is.
On edit: I put in my zip and UPS ground was $9.92 from CA to AZ. And when I tried a Michigan Zip, the shipping was $10.79.
