i know it dont look like a lot of tapes but my devil hunter alone is worth £300 plus

some are extremely rare

beast in heat £500
expose £300 +
Island of death £250+
Devil Hunter £300+ (on the red case - in excess of £500)

then alot are worth £20 - £50......then prices vary according to availability, desirability, quality and times of year (i.e xmas and credit crunches kill prices)
