I have the one:

I've been using it for over three years. Great stand for $80. Good welded steel contruction, can adjust/operate seat post clamp with one hand, can position the bike at any angle with good positive stops. The legs easily fold up for storage/carrying. I've taken it to the trailhead with me a few times for some last minute adjustments.
There were a few times where I wish the base was a bit wider. However, overall, it's a great deal on a great stand.
