I have the chance to buy a C drum for about $3800. The front has some pitting and the back is speckled with light pitting. I'm planning to go to the SAR show in Phoenix in December. Am I likely to find a better "deal" or should I take this one? All opinions wellcome. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/ph34r.gif
