I'll use current Binny's pricing as they dominate the market here in Chicago and everything's listed on their site.

$10-None...the only 2 listed at $9.99 are Zackariah Harris and Benchmark 8 at $9.99. HH 90 proof 6 year bought in Kentucky is what I drink.
$20-Barton 6 year BIB
$50-Booker's because I wouldn't pay the $49.99 for the current WTKS and Rare Breed is in the under $40 and loses to 4R.
