Not sure how many people out there use the magnetic markers from Alea Tools (aleatools.com) they are great for marking status conditions and got some nice press from the WotC folks a while back (Stephen Radney-MacFarland). They just fixed the one problem they had with the magnets being a bit too strong when used in close quarters. They are discounting old stuff and have conversion kits if you want to fix your current markers. I love these things - great tool got better.
