Where to find bistro tables for our bridal shows

Hi all... 

We have had a long time relationship with a local party rental vendor.  This year, our contact left and they are not honoring our past arrangements, so I think it's time to buy 2 bistro tables.  I've searched the net, but I haven't found anything yet... do any of you have any suggestions?  We always take two tables to the shows...

Thanks!!
