Pamps, Boro and Bansko prices are all there or there about. Not much in it really. However, if great snow, great skiing/boarding and better pistes you really want to go to Bansko.
I found Bansko very reasonable but I do wonder with each year progressing and it becoming more 'well known' whether increases will start. Will be interesting to see how March 2006 compared to this year.
BG is SO much cheaper in general though one can't really complain!
