I am wondering if anyone could give me some advice. I am looking at a Sig 150 or a VS rDNA40 for my next mod, however I am open to other suggestions. I am currently using an ipv Mini ver. 1. I am also looking for a mod with a side tank for my Hubby. He is currently using a VTR but it is not reading accurately anymore. I rebuild and we mostly use Kayfuns or Mini Buddahs. Any suggestions would be helpful. Thanks.
