Sorry i havent really tried much out with arcadebanners.com but i do however have a list of all the arcade exchanges which updates on weekly basis.
List of Banner Exchanges | FurPicnic - Arcade Information, Themes and Scripts
I even have the top 3 i recommend after testing them out. Also with such a low CTR you should try one of the free banners they offer. Your CTR should be around 5%. If you need any more info feel free to contact me.
Thanks and i hope this helps
