HH357 - The best dripping experience you can get without touching RBAs - and many (including myself) think the flavor is even better. They last forever as long as you take care of them.
Cisco Spec 306 and 510s - The best AFFORDABLE dripping experience you can do. A great place to start. 306s have a slightly larger learning curve and picking up a glass drip tip (something that is a must for dripping! You're doing this for the flavor afterall!) for them is a bit harder.
Ikenvape i06 - Another great affordable dripping experience. Jus tlike the 306 you will have a hard time finding a glass tip - but if you can get one these are great, flavorful and have a great tight draw similar to a cigarette.
