Bulgaria is quite cheep and cheerfull so i have heard. Would defo recommend Italy as Adam suggests though, but not the cheepest. Went boarding to Andorra last season, was really cheep, went to Arinsal, snow was crappy (was late season) but Pal and Arcalis (two mountains next to it) had really great powder. Really quite cheep too, well somethings wern't too cheep, like medical expenses - wish i didnt break my arm now!!! lol - hence a no no to Arinsal itself, AKA the ice mountain of death!!
