One I liked (even though mass market in Russia) is Baltika. Not that expensive, although anything liquor wise is cheap in Russia. Pretty tasty.

Best beers I had were in Belgium. Not that expensive (from a Canuck's standpoint, nothing in Europe is "cheap") on average, and very good. Could have a good pint to half litre for around 2 to 3 euros in most restaurants/bars. About the cost of a coke, but with much better taste
