whiskey, cognac, brandy

[yourchoice]

Okay, this thread is taking a cognac turn, so I will ask a question... I'm a very big fan of scotch. Scotch and gin are generally my two favorite libations. I am interested in trying a cognac (or brandy). Is there a reasonably priced, reasonably available cognac someone could recommend? I would hate to buy something that is subpar leading me to swear off cognac in the future. TYIA!
