This is starting to feel a lot like the computer industry (ie. 100 mega
hertz was
great at one time but they look pretty obsolete compared to a 1 giga hertz
processor). I was feeling good about 20 marker tests being in the horizon
but from what you state 50 markers is where things are quickly going. Geez...

Best wishes!
