I have the set you looked at on ebay. I like the 2 shelves because you are able to put other toys on the shelves almost like storage...good for younger kids who don't really move the pieces for making forts, ships, etc. yet. The ones with one shelf (like Elves & Angles) are better for children to climb over the shelf and pretend they are driving a boat or ship for example.
The quality of the ones on ebay is good. The only hard part was the dowels that go across the awnings. They were difficult to get in and to keep glued.
I have also seen the Elves & Angels ones in person. They are great quality, but they are smaller compared to the others. They sit lower to the ground and the awnings aren't as tall.
I actually own a Waldorf toy business, so I have seen several. I sell the ones by Little Colorado only because I can't sell E&A ones anymore since their fire. These are nice (and much cheaper) but they do not have awnings.
Good Luck in your search! You might want to look at PlayfulPixie.com -and- WaldorfWoodenToys.ca
