Heresy miniatures might not be around for much longer. If it went it would be a loss to the hobby as they are a fantastic company.
This site has beautiful minis and weapons for use in Necromunda, Dungeons and Dragons, Frostgrave, etc, so I recommend grabbing what you can while you can. The worst case scenario is you'll give a cash injection to an incredibly talented family man and his business.
Good luck Andy.
