Sorry Aaron, I stand corrected, I had assumed the OP was in Canada. My mistake. The same could easily be true in reverse. The AP cages I have seen are almost the same very well made and similar design. IMO many times superior to the RRE ones I have seen and looked at on the web site, I have concerns with the basic designs they have been using.
Op you might look at Vision as well David Northcott is a also easy to deal with. The roto moulded design has rounder corners and is easier to clean but the hard corners of my Sly has never caused issue.
