Need Mason Jar Tart Warmers!

I have a craft show coming up and in need of a few Mason jar Tart Warmers!  I am looking for a wholesale company and was hoping that you my blogging friends would direct me to one?!  I see lots of newer tart warmers out there...but, still prefer to keep my booth with a more primitive country feel and would love to offer tin & mason jar tart warmers to my customers.  So, if you know of any places that sell them...please send me an email.  Or if you yourself might be selling them second hand and in good condition...I might be interested too!
