Any suggestions in the $30 range? I finally convinced my wife to try good bourbons and she's partially hooked. Some she likes, some not so much. Her tastes have trended toward the $50-$75 bottles I've purchased

. Trying to find something she'll like in the lower range.
We've tried the following, with varying degrees of success (her reaction in parens):
- Bulleit (so-so)
- Buffalo Trace (no)
- Four Roses, think it was small batch (she liked this, but thinks we can do better!)
- Elijah Craig (similar to Four Roses)
- Woodford Reserve (so-so)
- 1792 small batch (just purchased, not tried yet)
As I recall, her favorite so far was Michter's small batch (about $50). I'm wondering if I just can't get something that she'll love at this price point. Any ideas, experts?
