I think that Sturmgewehr.com is the worst for pulling adds.Every ad I've placed was pulled by "BUDDY" and for the life of me I followed their rules as close as I could interpret them. He gives no reason as to why he pulls adds except :YOU NEED TO READ THE RULES". As for ebay I've been lucky so far.As for GB, Most items start at what they sell for on ebay. Just my opinion.
