I agree with the surmag 11 stilts they are in my experience the most comfortable, the only thing is that the brace around the knee the sponge/ foam padding gets very thin after a while and the plastic surrounding digs into the leg ( very uncomfortable ), on this web site they do a similar version to Dura stilts with an updated brace around the leg
All-Wall.com - Drywall Tools Superstore , its an american site but shows some options. Take a look at the magnesium ones as they are lighter than the aluminium ones. The Marshalltown 2.0 look good but thats it, they are very clumpy to walk on and heavy, the only good thing about them are the quick release system. I think the cheap versions of stilts that you see for sale are of the original Dura Stilt design but are made of cheap low grade metals that where away.
