Just talked to my BIL who was at mandolin camp all last week. His good one is made by Weber and is the F-style 10th anniversary. It is limited to only 10 being made, but only 4 have been made so far (one must order these things, apparently).

He got to play quite a bit with Evan J Marshall this past weekend, who is more of a classical (not bluegrass) mandolin player. Youtube has many cool videos of Mr. Marshall.
