Well that first set is insanely expensive. There are sets that are handmade, custom from sustainable hardwoord blah blah, but those don't seem to be of that variety.
We have the last set you linked to and I have been extremely pleased with them. FYI, I got them at AC Moore with a 40% off coupon.
FYI, the first M&D set you linked to are pretty small. If it's the set I am thinking of, the size of the blocks is much smaller than in your typical unit blocks set. That isn't readily apparent when viewing online.
