I've custom ordered some laser-cut chipboard base toppers to glue onto 3/4" fender washers to use for my infantry bases. Drilling a hole in the base of the infantry to hold a 1mm x 2mm rare earth magnet. It's a lot of time drilling and gluing, but I've got a lot of Godzilla DVDs that I'm watching while doing this!
I'll also put magnets under the carrier bed of the GEV-PCs so I can easily move infantry on and off the vehicles. And have stands for all the infantry since Minis Set 2 doesn't include stands.
