Use the Blue tomato Boardfinder
and see what fits u best, then try ur local Ebay or equivalent and find a barely used 2nd hand one.
I found my 08 Burton King 167 (used 3 weeks in total) for 50 euro.
I'd suggest getting a pair of new boots tho, since they have to form to ur feet.
I got my gear in the pre-season sale and 2nd hand for a total discount of 62%
