Cheap Dry Herb Vape?

I'm new to the world of dry herb vapes and the sheer vastness of the selection nowadays with all these minutely distinct portable devices that all do the same thing. I'm between the Plenty at the high end and the Starry V4 at the low. I'm looking for a balance of features like oven size, temperature range/control, type of heating (conduction or convection), and whether or not there are available accessories like dosing capsules, glass/whip adaptors, etc. What device should I buy?
