I actually found the best prices to be on their website when I was looking this summer.
I also used a pressure washer before to clean out the rockers, however I had mine cut open so access wasn't an issue. I was amazed at how much dirt came out!!
Thanks, yes, I figure they will be pretty dirty. I may drill a hole up top around the sill plate in order to spray it out and make sure the openings at the bottom allow the gunk to drain.
