They are all pretty similar in construction. One advantage of the Dobinsons is that it rolls out to 3m vs 2.5 from the other companies. For the price it looks to be a good unit. I ended up going with an Ironman 4x4 awning and it has been fantastic. It comes with an attached led lighting as well...might want to check it out, and they are in stock as of this post.
