Anybody have a Stinger stacker?

Like it says, anybody have or run one, and what do you think of it?

I looked at them a few years ago and liked what I saw - but that was about the time I started making less hay. I have never seen one up close, but I beleive the quality is there.

I'd rather have something like this, but all we do is round bales, not much for big squares here.

my neighbor has a highline 7 bale carrier like that one. I know he has had some problems with it though, but uses it a lot
