Aberlour A'Bunadh or Macallan Cask Strength Both very good B+ in my books.
$52 & $62 respectively and plenty of proof in either of these.
I know these are a bit more than your price point but these are both a step above the others you are looking at.
I happen to price shop constantly so you may find these at much higher prices in your area.
It amazes me at the huge price differences in the same scotch whisky from one source to the next.
