I have contacted Ferplast to see about getting one of these, but it would be very pricey, and P@H (who said they could get it cheaper) have let me down. So on the off chance anybody has just the platform/shelf with the attached ladder and could post it that'd be brilliant. If I remember rightly the lower Duna Fun level is the same, so that would work too.
I'd prefer to pay by Paypal, and would pay the fees.
I'm waiting for a cheque to clear, and would be able to pay from the 15th of June onwards.
