I do have a couple of sellers through ebay that I use all the time.. I also do not buy if they have less than a 98% feedback and I do not buy if they have under 20 on feedback...
So far I have been really happy.. I have found the material has been accurately described... Also the few I use do ship very quickly... Not only is it convenient for me to purchase from there it is ecinomical...I live 57 miles from any large town..
