Honestly very satisfied with G8 and D|S 4.2, but I have no interest at all in their subscription/content sale stuff since I generally make my own stuff and give it away, and I feel like G9 is a baffling collection of terrible ideas that make it much harder to make content for. It kind of blows my mind how D|S has become Actually Good, without need for any extra plugins, and how good it has gotten at things like dynamic cloth and rigging your own conforming clothing. I have a super modest machine (a 10+ year old HP business desktop with a very low-power fan-less video card) and it does pretty well for the fairly narrow focus I have for a posing and rendering environment app- generally I render one or two characters in a pretty simple scene, although I sometimes do some fairly complicated stuff with dynamic simulations and lighting. It sucks a bit at a couple of things (glaring lack of a morph brush or general purpose sculpting tool to reshape meshes comes to mind) but I regret very little of the time and money I've put into D|S.

Hugely valuable single items I spent money on:

G8 morphs

Skin Builder for G8
