I also recommend Charley's. They arent cheap but they aren't overly expensive either. You get what you pay for with them. Their products are well built and they will be there to help you if you have questions. The greenhouse I bought from them about 6 months ago came with a whole book that was instructions on putting it together and had pictures that went with most steps. If you join Hobby Greenhouses Charley's give a discount... I think its 5%.
