Hi, and welcome to the forum. You can't sell things here in the new members thread. You need to get 5 non-spam posts here before you can post anywhere else, but after you've done that, you could list them in the classifieds. Just chat here a little while then let the site update and you'll be able to go to other forums.
It's funny, sorta, because most people start with the 510 model and move UP to the eGo system because it has so much better battery life. If you have the funds to just hold off, I'd bet that within the month you'll be glad to have those eGo kits. The 510 is a nice little pv, but the battery life could drive you crazy after awhile if you're even an average vaper. The eGo (IMHO) kits are much, much more convenient and I think you'll get past the "looks" thing pretty quickly. If you can afford to, I'd just set them aside a little while; you may decide you prefer them once you get a little deeper into the
vaping scene. And all the stuff (attys, cartos, etc.) that you
buy for the 510 will fit on the eGos, so it won't be a waste of money. Just a suggestion. Good luck.
