theres so many choices available, pro tanks work well for vapor and flavor. Theres the Iclears that jayyco recommended. I've also been really enjoying the aspire tanks. The Nautilus is pretty high dollar for a tank but the smaller tanks work really well too, Ive got a few for $10 or so and they work a bit better than the pro tanks. It all comes down to personal preference and what works best with the setup and juice you are using. Maybe you will find that you prefer top coil vs bottom coil. Carto tanks are a little more work at first but the flavor and vapor is better than clears to me and they are very low maintenance.
