I like detail, but I'm not crazy.
From other discussion, sounds like Pendraken and Bend Sinister (and maybe GHQ) have the nicest sculpts.
Old Glory has the widest range -- at the moment -- although Pendraken has an ambitious release schedule for 2011.
AIM and Minifigs are offline while GFI resolves its internal problems.
Magister Militum figs seem to be very stocky, although different photos show different builds.
Thanks
