I stopped in at my local binny's with a friend to pick up the KCSB. Anyways, they had the Makers mark 46 available for tasting. I'm not much a fan of regular MM- its bland and doesn't really do much for me. But I tried this and was really blown away by the amoung of flavor and spice the oak staves added to it.
While I don't think it's really worthy of the $35 price range, it would be a great competitor with WT/BT/Weller in the 25$ price range.
I also tried the EWSB 2001 and did not think much of it (although the 2000 was very good).
