I highly recommend Chartreuse & Co and Sweet Clover - both are antique/vintage barns in Frederick, MD. They are fabulous and offer all kinds of furniture, much of it painted, for reasonable prices. Their sales are held once a month on the 3rd weekend, and the best way to preview their offerings is to check out their Facebook pages where they post hundreds of pictures prior to each sale.
I also find & paint vintage furniture here in DC if anyone is interested in a specific piece:
