This thread made me realize I need an RDA. I have no interest in dripping but after filling a tank with a new flavor and it tasted like doody, I need something for sampling new flavors.
If you have no interest in dripping...why not just get an old-school cheap atomizer, like a JoyeTech 510 shorty or one of the JoyeTech Ego Mega Cone Shaped ones or Cylinder Shaped ones? I use those exclusively for taste testing recipes when I make and tweak new ones.
The JoyTech 510 ones come in just 1 style usually still available now (with the mesh covered atty head). The JoyeTech eGo Mega Cone Shaped ones come in 2 styles/types - (1) those that have just the pointy tip of the atomizer head sticking up in the bottom of the cylinder...that the end of a plastic tank punctures itself on to release eliquid from it, and my favorite (2) those that have an atomizer head point that's mesh covered. You just use a Type A drip tip and drip a few drops at a time on it. Gives a wonderful true taste and it's easy to burn off that flavor when it's time for the next one you want to test.
I got a ....load of the JoyeTech Mega Cone Shaped ones at The Vapor Room on clearance for $.50 each! They have the Type A mega drip tips to fit them, too, for only $.10! Even at those blow out prices...you can still use the code (thankyou) at Checkout, to get 10% more off your total purchase!
Here's a link to the JoyeTech Mega Cone Shaped Atomizers, still available in 1.5 and 2.0ohms resistance, in a variety of colors at the Vapor Room:
