Your bump was a good idea, this thread needed to be awakened from the dead!
Casa Noble Crystal is worth the search, it's amazing and not too highly priced. In the mean time, don't hesitate to try either Don Julio or Don Eduardo, both very, very good/excellent!
I drink a lot of Tequila after meeting my inlaws, wife is from Mexico, and the best blanco out there is still Casa Noble, according to them and me.
