I know a few people that have been to Bansko in Bulgaria and said it was pretty good. Maybe have a look at that?
Andorra is cheap(ish), too. Pas de la Casa is the main resort there.
Thanks for the suggestions...I checked out Bulgaria and it looks like a much better and even cheaper option that the Czech Repub. The resorts I saw there look pretty cool too. Not too much advanced riding but the Apres' scene could make up for that. I'm going to research Andorra this weekend.
