i was the same way, i sold most of my tanks and bought a couple of rebuildables... found out that me and rebuildables dont play well togather so i tried a few more rebuildables and didnt like them either. i had a couple of phiniacs and a kir trap tank left so i sold the rebuildables and bought a prive and a prive varadero and havent looked back. i get my cartos at surevapes in a bundle for less than a buck per carto.
