These 3 classic officers are up for auction on Ebay at the moment. These older style sculpts look a lot better than anything released recently. Even if you have to field lines of the new plastic guardsmen, a couple of these guys will make them look just that little bit better.
I'm painting and buying using a points system now. This basically makes me sell off a few bits of my collection before buying new stuff. OK, it probably won't reduce the collection, but it should halt its exponential growth!
