Just looked at them tonight at Waldy based on your recommendation. They go for under $10 and I may have to pick up a couple. They get good reviews from what I can tell, and although the compass seemed to work on the one I checked, it was tiny and looked cheap.

Just curious how big you are... at 225, I'm not sure the extension joint locks would be tough enough for me.
