When I first started looking at them, 10-15 years ago, the price was about $999, now they are on sale for $999. Not much of a jump in these crazy times. I never tried one. I seem to remember someone having one here. Back before the big hack when we lost all of the old pics and video's. I just thought I could make one cheaper. After I covered almost every spot in my yard with slabs from my Alaskan, I kind of forgot about that one. I do like the idea.
