I own one, for the money invested I think it's a worthwhile addition. I originally bought mine because wife showed interest in joining me, and rather than invest in a DB right off the bat, the YT fit the bill.
Mine's the small one - if you have the choice go with the bigger one with the low cut windows in the corners.
The fabric needs to be "dirtied" up a bit, but I've killed two deer out of it without issue.
I'd love to get a DB one of these days, but for now my YT works just fine.
