Determing The Where Clause At Runtime

I am trying to set the WHERE clause in an SQL statement at runtime using a case statement like so

SELECT *

FROM table

WHERE   CASE @BrowseBy   
             
          WHEN 'Supplier' THEN
Supplier = @Value
           
            WHEN
'PriceRange' THEN Price > 1000
           
            WHEN
'BladeSpan' THEN BladeSpan = @Value
           
            WHEN
'MotorFinish' THEN FinishID = @Value
           
            WHEN
'BladeFinish' THEN BladeFinish1 = @Value or BladeFinish2 = @Value
                  END

the above code gives me a syntax error... does anyone know of another way to accomplish this?

Thanx
