Yup, I agree -- Reaper is the way to go, especially if you want to paint them. Another option is the Wizards of the Coast Chainmail line -- they\'re now out of production, but you might be able to pick some up at huge discounts.
(For use in D&D, I really do like the new prepainted line that WotC is putting out -- there is a stat card for each figure which makes running combat very easy. The paintjobs are nothing compared to what any decent painter can turn out, but you can carry a hundred around in a shoebox without worrying about paint chipping or miniatures bending, so it\'s great for spur-of-the-moment DMing.)
