I saw a clearance sale the other day and picked up 4 old drippers for like $25 shipped. I just wanted a couple to screw around on mainly and one of them to swap parts with something I had already. But, I'm still sitting here with a Griffin, Haze, and Avocado which I regularly use all 3. I have a second Haze on the way (prettier with glass tank), another mini RDA, and a Diablo. I needed at least one more quality mod to put them all to use, so I have those on the way now (RX200, and threw in a Noisy Cricket to play with).
