Descent and descent 2nd ed are ok - non heroic 28mm, d&d adventure system (legend of Drizzt, Castle ravenloft and wrath of asharsldon) are softer on detail and are massive, I.e. Heroic 32mm but not prepainted.
My main painting output of late has been a combo of descent, adventure system and reaper bones, they're all nice but not brilliant, much better than the D&D prepaints though but need their bases hacking off and replacing wilt slottas if you don't want them to warp
