I've done the exact opposite of you, actually. I started with a DynaVap (M and then got an OmniVong XL) and then just recently purchased an ArGo. I really like the ArGo for portability, and the removable 18650 battery is a pretty great feature, and it's super easy to clean. It definitely doesn't produce very dense vapor, but it sure tastes good, and I find it to be good at what it does at least. However, if I'm at home and portability/stealth is not a priority I'm always using the DynaVaps. The vapor is just incredible and with a little technique you can produce what ever vapor type you like. I think I'll probably be searching for a desktop unit in the coming months. I'll probably be scoping the sub for recommendations at that time.
