I used to drink a lot when I was a student in Poland (it was about 5-6 years ago). Being a poor student you don't turn your nose up at anything that has alcohol in it

. As I now remember, we used to buy Zubrowka (it's not a dry vodka - it's similar to whisky) -- just because some females would drink it too

. It was good though -- pure 40% of alcohol and it had a straw inside to make the taste rich. On other occasions, we liked "The [white] Polonaise" - it was for guys only, 50%!
But most of the times we had the cheapest ones (doesn't mean the worst), like Wyborowa, Czysta, or Absolwent. After three or four shots (one "shot" in Poland eqals two "American" shots

, you won't feel the difference.
The important point was to make the vodka real chilly (put it in a fridge before use) -- that way you'll be able to drink about 20% more than you usually do. Also - eat plenty of foods between shots (i suggest Polish sausage and bread). It will make your body to become less "drunk" overall.
When we become "rich", we could afford to buy Chopin vodka. We liked "Zoladkowa" too. But I don't see much difference between "expensive" and "less expensive" Polish vodka. Maybe because I've already lost good taste :--)...
