I have a few minis myself, and am in the process of repainting some (after 10 odd years of sitting on shelves!).
There are larger scale models of those lead minis, but some will cost you an arm and a leg.
The game seems like it is going through a "renaissance" period, with new minis coming out every few weeks.
