If you have the time this is well worth a visit.You might come away with nothing but its like being a kid in a sweet shop.
I have bought many items from these in the past and although prices are going up there is always something of interest.
I came away last year with a peach of a air rifle.It was only good to have on display as the pressure container was badly warn but at £80 it was a fraction of what it would have cost at kranks and such.
Make a day of it and you will enjoy yourself.
