About Cabbage Patch Kids I was lucky. I got it from Yahoo Auctions Japan for only 400 yens 
I'm looking for complete: Magical Tree, Comic Backery, Kings Valley 2 (MSX1) and Konami Games Collection 2,4,Special
Looks like it's about to be a war at eBay, when sellers launch their Konami's to bid.
Someone is going to buy a new car...
break-in @ bifi? ^_^I think break-in @ wolf's studio would get you stuff worth more 
even though for me the value of those konamis are higher...

at least now they know what they can expect
