Ha Ha thats so funny. Actually one of my fafourite ebay sellers do that kind selling, but i dont never buy them. What i buy from him are new untouched kits, witch are low priced in his store and he dont try to rob you with shipping costs. So i think he is good seller even with that funny part selling.
I buy mostly my kits from Dennis (Modelexpress) I got best service from there, he is very fast with shipping and prices are good. AND reason why i buy kits overseas are our ridicilous prices here in Finland. Imagine that i can have 2 or even 3 model kits shipped to my home door in same price what one brand new Revell kit costs here local shops.
All in all evilbay can be good place to deal but it can be bad too. Best way to use is just pick your fafourite sellers and deal only with them... Amen
