I would buy Ebaybanned items, but probably not Ehobby items unless they were the same price or a tiny bit more.
My reasons are: first, Ebaybanned is a nightmare to deal with and I will never order from them again. Second, any reasonable markup would be fine with me to avoid the horrible thing they call customer service and actually shipping your items sooner than a few weeks after you buy them.
My reason for Ehobby items is that I've had nothing but good experience and good customer service from them, and I've ordered a LOT of shit from them. Their shipping times are also decent (7-10 business days, everytime).
