Just to offer up an alternate choice....Gold Hog Multi Sluice. It seems there is not much difference in prices and the GHMS is very highly rated from all of the reviews I have seen. In my mind, the downside for both choices is that they require feeding with 1/4" minus material (read, I hate classifying!). That said, I think the main advantage of the GHMS when used as a high banker in the field is that you will end up with much less concentrate to deal with later.....better concentration and probable better gold capture rate. When you are home, change the mat and run the concentrates again and the result is almost 100% clean gold according to all reviews.
Good luck.
