Good Ebay sellers to buy Tiaras

Hi ladies, I'm back at square 1 getting a tiara after my SIL's won't match my dress & it has gold tones in it. Yet I don't want to spend a fortune buying one.

I was going to buy on ebay but have heard from some girls that the quality of some sellers isnt exactly the best.

Can you recommend GOOD sellers if you bought on ebay (or other reasonable venues)?

Thank you!!
