a few of us HAVE written "Books" about it already. ON this page. Look for the older topics. Including one that was just a week ago, although the better ones are a while ago. Search for "ryedale" and Im sure you'll find them. :-)
I"ll say again that it is THE best machine I own, bar NONE. Better than my White's DFX, my old White's Spectrum, my underwater, my two box, and my sluice all put together! Why? Well, read the older posts and you'll see why.
But I give it a 10 on a scale of one to 10, and would give it more if it wwere possible to give more (Sorry, I don't write things like "I give it 105%. It only goes to 100%, so that is all I give it. And I give the Ryedale 100%!!!)
