I had a DM that had spent a small fortune on Ral Partha and Grenadier miniatures, having gotten into lead and pewter minis early. He had a mini for everything, but the problem was they were all 25mm scale, while most modern Reaper minis (and the official plastic D&D minis) are the larger 28mm scale. And even then, there's been some size creep: I have some dwarves that seem to be pushing six-feet. It's impressive how small older minis are compared to newer sculpts, with humans seeming to be the size of halflings.
So what did this DM do, stuck with boxes of miniatures that would be laughed at when placed on the table, with my tall human mini towered over his teeny ogres? He made us all find 25mm scale minis and use those. He was nice enough to find a couple for us and give them as gifts. And it's not that hard finding old minis for reasonable prices on eBay. And during a European trip, I stumbled into a Geneva gaming store bursting with old Ral Parthas and found the perfect mini for my wizard.
While I've been in a lot of games where the DM restricted rules options, that was the only game where we had a restriction on PC tokens.
