We no longer sell the ATC, as it is not a Canyoneering device, but I thought I would leave this here as a link to an interesting bit of history on the CUSA Tech Tip linked below.

And just so people know, if you show up to a canyon trip with an ATC, you shall be frowned upon, righteously. It is like showing up to a gun fight with a peanut butter sandwich. Although sometimes I bring one for belaying, or because it is a Grand Canyon trip and every ounce counts!

A truly stellar plate-style rappel device, the ATC-XP works especially well on small diameter ropes, and offers a variety of modes for different levels of friction. It is compact, and my device of choice when we are not doing very many rappels, but I like the Critr or Sqwurel better for more technical ropework. 

Good Harness at a Good Price

The Versa2 is a decent, adjustable leg loop harness designed for climbing, and is now my go-to harness for canyoneering with the addition of a ShuffleButt. Well proportioned, comfortable, "gear loops", reasonably light weight. The main webbing is small but stout and holds up well.
