Wanted - Batman GX4000 bare cart

[tjohnson]

I'm still working on my Gx4000 collection and seeking a bare cart of batman for GX4000.  @ComSoft6128 kindly gave me the box for it but I do not have the cart.  There was one on ebay a couple of weeks ago but I thought the £30+postage he wanted for just the cart was too steep for me and people trying to sell boxed copies in Europe for 1000 euro are off their heads.
Can anyone help?
