Hey I'm glad you bumped this thread tacdusty. I spoke with a cell phone engineer at Motorola yesterday morning about this issue. He said
1) DROID production is at capacity in China so all the screens being manufactured are going into new DROIDS, none left over for the aftermarket
2) several other models in the pipeline are using the exact same part for their touch screens, thus increasing the scarcity
3) Motorola apparently has a warranty on the glass and will repair it for you free of charge within a certain time of purchase, maybe up to one year, maybe less.
Check this site for more info and to find a service center near you:

It's almost certainly a mail-away deal. I'm in the process of becoming a Motorola service center because there are none in the Baltimore-Washington area.
