I absolutely love my Loggy. Here's the link:

I don't care for the climbing aid. My friends and I prefer to use it as a one piece. It's small, compacted and secure. Once the seat is locked in, it can't move a bit. When your up 30' +, that's nice to know. It can also be a lock on and I have used it as such in a few areas.
