I am looking for a good set of large, natural, maple blocks for my three year old. Has anyone purchased blocks from either http://www.oldfashionedblocks.com/403.html, or Educational Concepts? And if so were they worth the price? They offer alot of unique shapes in their unit sets, but they seem a bit pricey. I am looking for something solid, and long lasting, and, preferably, with unique pieces like the Gothic Arc. Thanks!
