144 has long been a defacto 'standard' for track cranks. You'll find the greatest selection of used 1/8" track specific chainrings in this bcd, plus you're more likley to be able to borrow/lend rings with others at the track.
Miche cranks use 135bcd (limits you to Miche brand in 1/8") and other brands eg stronglight use 130bcd. If you don't want track-specific rings then note that Campag road are 135bcd and Shimano road are 130bcd and are generally cheaper than track-specific 1/8" stuff.
'track specific' usually means 1/8" (though you can get 3/32" also) and no ramps, pins, cutaways etc for shifting.
