Target stores do/did carry a line of Riedel's (Vivant--I think they're called), which also included the bourbon glasses. There's a thread about them in here, somewhere. I think they are pretty well priced if I remember the discussion correctly. You might try there, too.
Yep, that ETL is very good bourbon. Hard to go wrong with that one. From what you've described, I think the Eagle Rare 10yr Single Barrel might fit your palate, too. Should be just maybe, 5$ more than the ETL.
