Hi all - bought the basic package because I have the batts and such. But at the time I didn't have the option of adding a 510 tip. I had to buy the night they went on sale, you know. Did anyone buy a package with a 510 tip they don't want? I don't want my 801 and am willing to trade or buy a 510 tip from someone. I know they'll likely be available for purchase separately at some point but I just don't want to wait. Thanks!!!
