You should keep on keeping an eye on ebay (just do pre-slotta or old citadel or 1980s citadel searches as not all sellers know what the figures they're selling are in detail) and also take a look at the Miniature Heroes website.
Seen and/or bought all of the regiments on ebay at some point and bought some of the pre-slotta ones before that when i was at school. Most of the slotta versions were way inferior to the pre-slotta versions.
The slotta Golfag's Ogres were unusual in being better than the pre-slotta version.
