Chopin all the way; I'm lucky enough to live near the CAN border; picked up a few bottles at the duty free when currency exchange was ~40%...came to around $15/20 a bottle
I have tried a lot of Vodkas, but Luksusowa has remained my favorite for decades. Yes, I a have tried Grey Goose, it is good, but not near as good (IMNSHO)!
